Case Study: One-of-a-Kind Packaging

A Packaging Journey

From Zero to Success

Founded by a physician, TouchZero™ is changing the way we clean—by reducing exposure. While developing their unique cleaning solution, the brand team realized that the packaging would make or break the success of this innovative product. Here’s the story of how they landed on a package that is both functional and attractive… oh, and patented.

The Product Background
These days, the words “cross-contamination” have become part of everyday conversation. As we were all whistling the ABCs while washing our hands, the team at TouchZero was busy developing a one-of-a-kind cleaning product. They saw the need for something that would thoroughly clean surfaces and didn’t require gloves… but would also protect our hands. Enter TouchZero Wipes.

"

If there’s one feature of CarePac I really enjoy, it’s their responsiveness and availability. They were always there via email and phone anytime I had a question.

Touch Zero

The Packaging Need
Packaging for the wipes was essential to the use of the product. TouchZero needed to find a way to maintain the integrity of the cleansing solution on the wipe while also providing a means to keep the user’s hands untouched. A well-designed, functional, and easy-to-use package was a must.

easy peel pouches Case Study: One-of-a-Kind Packaging

The Successful Solution
After ordering samples from CarePac, TouchZero knew we could produce the right deliverable. Together, we set out to develop the perfect pouch. We determined that heat-sealing edges were critical to keeping the wipe operable. And the actual packaging material would act as the “glove” or barrier between the hand and wipe. The solution? A groundbreaking and patented disposable pouch.

Like TouchZero, you’ve worked hard to get your product right. The time and effort you’ve put into all the details are noticeable… and now it’s time to show it off in the best package possible. We’re here to help—get in touch by phone (via a real person!) or through our contact form.

Case Study: Packaging That’s Fresh as a Noni

Keepin’ It Real

Say aloha to the Frailey family. They are self-proclaimed “noni-obsessed” and their goal is to share the goodness of this Hawaiian fruit with the world.

To do this, the Fraileys needed to find the right packaging to seal in the pureness, portray the beauty of the fruit, and lay flat for easy transporting and displaying. See how we worked together to create the perfect package for this fantastic superfruit.

What Is Noni?
A love of wellness runs in the Frailey family—and the superpowers of noni are too good to be ignored. Used for centuries in Polynesian cultures, this tree-grown fruit packs a powerful punch of anti-inflammatory and antioxidant properties, providing our bodies with many healing and renewing benefits. However, before the family could share their passion, there was one hurdle in the way: to maximize the potency of the fruit, it needed to be captured in raw form.

Noni’s Packaging Needs
The Fraileys put their pro-noni noggins together, and after years of research, growing, and testing, they discovered a way to preserve raw noni—and their company, Real Noni, was born. But in order to get the fruit to their customers, the packaging had to be just right. They needed something that could maintain the freshness of the fruit and align with their quality-first approach while also being as beautiful as the fruit itself. With this in mind, they set out to find their perfect package.

Noni-Worthy Results
After a failed attempt at getting their dream package from an overseas company, Real Noni turned to CarePac. Working together, we found a pouch that ticked every box—exceptional (and BPA-free) vapor and oxygen barriers, FDA Food Grade compliant, reclosable, and custom printed to capture their vivid colors and stunning images. The result? Beautiful packaging and happy customers… a noni dream come true.

The team at Real Noni understands that packaging can make or break the success of a product. Not only is it needed to protect your prized possession, but it’s also an essential marketing tool that should speak to your brand and attract customers. As packaging experts, CarePac works with all different types of industries and will find a solution for your needs. Get in touch by phone (via a real person!) or through our contact form.

CarePac icons infographic Artboard 7 Six Tips when buying flexible packaging

CarePac icons infographic 01 Six Tips when buying flexible packaging

Tip #1: The cheapest pouches aren't necessarily the least expensive product

If you’ve bought pouches, you may have discovered that the cheapest bag won’t necessarily save you money. Every day, we work with customers who are trying for the second or third time to find good quality containers. Maybe they’ve bought cheap pouches sourced from overseas or click-and-print websites that offer no support… and they’ve learned that pouches made with inferior or inappropriate materials won’t attract customers or keep your product fresh. But they will damage your brand. Always work with a supplier who’s ready and able to help you consider your options and takes as much pride in your success as you do.

CarePac icons infographic 02 Six Tips when buying flexible packaging

Tip #2: Look for suppliers with a wide selection of stand up pouch types

How do you know which suppliers to trust? Look for the variety of options they offer. One size does not fit all! Different products need pouches of different sizes, made of different base materials to keep the product fresh, safe, and looking great. Stick frozen food in a pouch designed for trail mix and you’re going to have a lot of unhappy customers. At CarePac, our website offers a detailed industry-by-industry guide to applications – from baby food to pasta, from bath salts to vitamins – with options for nearly fifty different product types. Whatever you distribute, we can tailor pouches to suit your needs, including the latest in eco-friendly packaging. We have the machinery and packaging materials necessary to do so.

CarePac icons infographic 03 Six Tips when buying flexible packaging

Tip #3: Insist on a reliable, timely supply

Don’t wait for a surge of sales to discover that your packaging supplier can’t deliver in quantity and on time. You can’t afford to work with firms that are desperately trying to keep up with demand or who won’t work with you because of smaller order sizes. At CarePac, we offer flexible lead times to meet different customer budgets and deadlines, with shipping in as little as four weeks for custom prints and two to three weeks for stock pouches, with orders as low as small as 1000 pieces.

CarePac icons infographic 04 Six Tips when buying flexible packaging

Tip #4: Look for high-quality, flexible printing

Your packaging is your calling card. It deserves better than washed-out inkjet labels, and you deserve professional printing services that can match your vision. At CarePac, we offer three printing methods – digital, flexographic, and rotogravure – so you can pick the type of printing, materials, and films that best fits your project. You can even add a logo to your specialty packaging in one simple step.

CarePac icons infographic 05 Six Tips when buying flexible packaging

Tip #5: Don’t take a chance on compliance

FDA food contact, BPA and Phthalates free, REACH, and PFAS: there are a lot of compliance and sustainability requirements in the marketplace… and a lot of unreliable claims that materials are compliant. Your chosen supplier must be able to verify to your satisfaction that your pouches will pass muster.

In the next section, we will discuss common materials we use in our pouches.

Common Dog Treat Packaging Materials

As mentioned above, the best materials for dog treat packaging are those that are durable, cost-effective, and have a low impact on the environment. Learn more about our materials below.

CareFoil

CareFoil offers the highest barrier, which means it has the longest shelf life. It is good for printing and will protect the pet treats within from spoilage. CareFoil prints well and will ensure your treats are well preserved and look great.

CareSilver

CareSilver is a metalized PET lamination in the line of a mylar type material. Which provides quality oxygen and moisture barrier at a economical price. It's a great base for printed pouches that helps colors come to life.

CareClear

This material allows for a viewing window but has a lower barrier than both CareSilver or CareFoil. As such, it is best used for short-term storage. This material is also an economical choice and is one of the packaging options that can help lower costs.

CareClear-XP

Treat bags made from this material provide an enhanced barrier material, which can help increase the shelf life of your dog treats. This product still allows for a viewing window and can help your packaging bags stand out on the shelves.

Sustainable Materials for Treat Bags

Last but not least, don't forget about sustainability!

Unless you've been living in a dog house, you've probably noticed the growing trend of customers caring more and more about supporting a business that uses eco-friendly materials. This applies to dog treat bags, too! When selecting a packaging design for pet food, it's important to use these types of products.

Biodegradable, compostable paper, and recycled materials are all things that customers care about for both pet and food products. Fortunately, CarePac specializes in designing and manufacturing dog treat bags that use eco-friendly materials.

Tips for Sealing Mylar Bags

Mylar Bag Sealing: FAQs

Sealing your mylar bags after loading them is the critical last step before your bulk product is ready to leave your facility and journey to your customer. If your printed mylar bags are not properly or adequately sealed, your product could fall out of its container or prematurely go stale in the pantry, neither of which is ideal for your customer.

Types of Food Storage Sealing Options

When it comes to properly (and professionally) sealing mylar storage bags for storing

long-term, there are four different options: impulse sealing, direct heat sealing, band sealing, or chamber vacuum sealing. Each has its own pros and cons, which you can learn more about below.

Impulse Seal

Impulse seals are inexpensive (starting at around $30 - $100) and provide a quick seal using a pulse of energy through the seal bars. Impulse sealers only turn on when the sealing bars are lowered onto the vacuum seal rolls.

Positives	Negatives
Inexpensive	Less control that band sealers
Instant Sealing	Small Seal zone
Best for occasional use	Manual bag line up creates inconsistent seals

Manual Foot Pedal Sealing Machine Direct Heat Sealer for Bags and Films with Printer and Heating Sealing Machine and Impulse Sealing Machine

Direct Heat Manual Seal

Direct heat sealers maintain consistent and constant heat as long as they are turned on. This can allow for better heat penetration and better seal tack.

Positives	Negatives
Best for thick materials	Cannot seal polyethylene
Industrial bags o irregular bags	Slower than band sealers

Band Seal

A band sealer is a semiautomatic sealing machine. Unlike a manual sealer, a band sealer contains both heating and cooling elements. The hot and cool elements combine to create strong, durable, and professional seals on your bags. These direct heat-style sealers typically have separate controls for both temperature and dwell time. A small conveyor with speed controls will pull your bag through the sealing mechanisms, and once set up, hundreds of bags can be processed at one time.

Positives	Negatives
Very consistent seals seal hundreds of bags in a single use	More expensive $500+
Accessories such as date code, serial number stamping	Not ideal for sealing a few bags occasionally

Chamber Vacuum Seal

Chamber vacuum sealers can be used to seal certain types of mylar bags. These machines are different than the traditional “at home” or food-saving type vacuum sealers that are used by preppers in their home kitchen to vacuum seal bags. A chamber vacuum sealer will both vacuum out most of the air from the bag and also heat seal it at the same time.

Positives	Negatives
Removes oxygen from the pouch extending shelf life.	Not compatible with all materials.
Print can get distorted when the bag is vacuum sealed.	Quality chamber sealers start at around $850.

Sealing mylar bags with an impulse sealer

If you have an impulse sealer, here’s a visual of how you’d use it to seal a mylar bag. We’ll walk you through the process step-by-step below.

Heat Sealer Heat Setting- Food Storage

The question is often asked “What temperature setting do I use to seal my bags?” This question is pretty straight forward but the answer to it can be effected by many variables. Setting your heat-sealing machine to the right temperature is only one factor. Other factors include how long heat is applied to the material (dwell), and how much pressure you apply while sealing. One temperature, Dwell, and PSI setting is not uniformly recommended for each material. For example a better seal can sometimes be obtained with a lower temperature allowed to dwell longer allowing the sealant layer polymers to fully melt together.

Material	Temperature Setting Range	PSI	Dwell Time
CareSilver (VMPET)	350F - 400 F	40 PSI	1 Sec
CareFoil (Aluminum)	400 F - 450 F	40 PSI	1 Sec - 1.5 Sec
CareFoil-N (Nylon)	450 F - 500 F	40 PSI	1.5 - 3 Sec
CareKraft (Kraft Paper)	400 F 425 F	50 PSI	2 Sec
CareClear (PET)	350 F - 375 F	40 PSI	1 Sec

Factors effecting heat sealing settings to use

Many customers focus on the machine settings when dialing in their heat seal settings, but all the factors below should come into consideration to get the highest strength heat seal.

Material Type

Seal strength, and sealer machine settings will be adjusted to the physical properties of the material being sealed to. Clear PET based material generally will use different settings than nylon or foil based material. The material thickness, flange or surface design, physical pouch configuration, size, and feature placement will also be considerations. Some materials like Carefoil reduce the amount of heat that can get through to the sealant layer so they require more heat or long dwell time. Material Thickness can effect the overall mount of dwell that is required.

Dwell

Dwell time relates to how long heat is applied to the pouch. Heat and dwell time are not independent variables, they go hand in hand and should not be evaluated separately. Dwell time requires adjustment based on the same factors that effect temperature. Some heat sealable flexible barrier materials require lower heat for a longer time to properly sell. While you can "seal" a bag with high heat for a short duration. The sealant layer may not form a high strength bond.

PSI

The pressure at which heat is applied to the pouch can effect bag seal strength.The amount of pressure applied by the heat-sealing equipment will create differences in the heat and dwell settings. Thicker materials and those which are more rigid such as CareKraft require more pressure, while with thinner materials if too much pressure is applied the heated selant layer can be pressed too thin.

Fouling

Fouling can occur during the loading process particles, dust, or liquid we left in the sealing zone. If so, these contaminates can affect the settlings required on your sealing machine to seal the bag properly. Foreign material in the seal zone can also reduce the seal effectiveness. Powder products are notorious for causing fouling. Dust acts like corn meal on the bottom of a baking pan inhibiting the polymers from adhering to each other.

Type of Machine

The type and condition of your heat-sealing machine will create another variable to consider. There are several types of heat-sealing machines and how these machines apply heat. Types of heat sealers include Impulse sealers, roller sealers, platen seal.

External Environment

There isn’t going to be an exact specification because proper temperature will vary widely based on the conditions mentioned in this article. But here are some of the settings that have been reported to us by customers, as well as our own understanding.

Tips for Sealing Mylar Bags

If you’ve never sealed mylar bags before, here are some tips that can help:

The exact dial setting will vary depending on the thickness of your mylar bag, the ambient temperature, and whether there has been any fouling (foreign debris) that got into the seal area.

Start with a lower setting and work your way up. You’re looking for a “just right” temperature where the inner sealant layer of the mylar bag fully melts together, but not too hot where the bag is deformed or fully melts. If the seal is too cold then the sealant layer will not fully melt together, and you’ll have a very weak seal.

If you pull too much of a vacuum on your mylar bag, you’ll rip the bag. To create a high vacuum, certain types of mylar material like CareSilver-PVNP must be used.

Some products are very oxygen-sensitive, and exposure to oxygen causes oxidation and spoilage. An oxygen absorber can extend the shelf life of these products.

An optional step to seal your mylar bags is to perform a nitrogen flush. With nitrogen flushing, the sealing machine will first vacuum out most of the air from the pouch, then replace it with.

Mylar Bag Sealing: FAQs

Here are a few of the questions we get a lot about sealing mylar bags for food storage. For more information, feel free to contact us directly.

Q: What thickness of seal should be used?

Impulse sealers typically offer 2mm, 5mm, or 10mm seals. While thicker is usually better, you’ll want to adjust the thickness based on the type of product and bag. A 2mm seal is usually only suitable for thin polybags, most mylar bags should have at least a 5mm seal applied to it (for prospective ¼” is about 6.35mm), a 8mm or greater seal is often required to prevent bag bursting.

Here are some typical considerations:

Matching the other seals on your bag.

Sealing the entire “top” of the bag is sometimes required.

Note: make sure that you never seal through or below the tear notch. Doing so will make your bag unable to be opened except by using scissors.

Q: Do you have to vacuum seal mylar bags for food storage?

No, you don’t.

Q: What foods cannot be stored in mylar bags?

Although most foods can be stored in mylar bags, there are some exceptions. Foods high in moisture or oil (raisins, nuts, granola, cookies, chocolate, crackers, brown rice) are not good candidates for storage in a mylar bag.

Q: Do you need a special vacuum sealer for mylar bags?

Yes, you’d need a chamber vacuum sealer. At-home food saver sealers cannot seal these mylar bags because they require the bag to have an embossed pattern to fill the air.

Q: How much heat does it take to seal a mylar bag?

It varies. You will likely need to go through a period of trial and error before determining what amount of heat is required.

Q: Do you offer custom sized beauty packaging?

Sealing bags for food storage is similar to sealing bags for retail. The key consideration includes investing in an inexpensive impulse sealer and adding oxygen absorbers, if necessary.
