ClearBags Barrier Packaging Explained

What is Barrier Packaging and Which is Right For You?

Why barrier packaging?

Barriers protect what's inside your package. By limiting the exposure to oxygen, moisture, and light, barriers keep products fresh for longer periods.

Products travel safe and are well-protected on store shelves with the help of barrier packaging. Stand up barrier pouches are especially popular for flavorful and aromatic food products.

Flexible plastic films also offer a wide range of barrier protection and offer many advantages over glass or metal. Plastics offer flexibility in design and shape, and they are lightweight and inexpensive. Many plastic films are heat sealable and are easy to print on.

The disadvantage of plastics is that they are permeable to light, moisture, and gasses. This is where the use of a barrier comes in.

What is a barrier?

A barrier is anything that blocks passage, and this includes what leaves or enters the package. A barrier functions to help products:

• Keep desirable flavors and aromas in.
• Keep undesirable moisture, oxygen, and gasses out.
• Prevent migration of moisture, oxygen, and gasses from within the film into the packaged goods.

How is a barrier measured in packaging?

A barrier's performance is measured by the Oxygen Transmission Rate (OTR) and the Water Vapor Transmission Rate (WVTR). The lower the transmission rate, the better the barrier performance.

The company is the world’s best Fold-over flap OPP bags manufacturer supplier. We are your one-stop shop for all needs. Our staff are highly-specialized and will help you find the product you need.

The ability level of a barrier is determined by the transmission of molecular gas (O2, CO2, N2), water vapor, and other organic solvents.

What are the different levels of barrier protection in packaging?

A barrier can consist of single layers, double layers or multilayers of coated films. Single-layer films are permeable to most gases, so added layers will improve the barrier strength.

Our barriers fall into four categories, ranging from low to very high.

1. Basic - single layer
2. Basic - double layer
3. Moderate
4. High performing

Let's take a look at how these different barriers measure up.

Basic Barrier - Single Layer

Basic barriers with a single layer are food safe and perform well for general packaging.

Here are the type of materials you would find in this barrier level:

• Polypropylene (PP): including CPP, IPP, OPP, MOPP
• Polyethylene (PE): including High-Density (HD) and Low-Density (LD)
• Polylactic Acid (PLA)

PE and PP materials both provide a moisture barrier. The PE bags are clear, soft, and flexible and provide good heat sealing capabilities. The PP bags provide high clarity, high gloss, and excellent tensile strength yet are not as breathable as the PE bags.

When blended with polymers such as cast unoriented polypropylene (CPP) and biaxially oriented polypropylene (BOPP), the PP bags have even better clarity and heat sealing performance.

PLA is a polylactic acid that is derived from plants and provides a medium oxygen barrier and a low moisture barrier.
Popular products and uses: Includes most of our plastic bags used for food, retail, transporting goods, and general packaging. Our Crystal Clear Bags made with BOPP offer an exceptional presentation for food products.

Basic Barrier - Double Layer

A basic barrier with two layers is often associated with laminated packaging. You may see this combination of materials in a double-layer barrier:

• PE/PP Lamination
• PET/PE Lamination

Materials like PP and PE are combined to create a stronger moisture barrier. Polyethylene Terephthalate (PET) provides a gas and aroma barrier as well as a moisture barrier.

Popular products and uses: Heavy duty gusset bags and heavy duty heat seal bags for grains, nuts, and heftier products; stand up rice pouches and kraft stand up pouches with laminated inner lining used for cookies, candy, coffee, snacks, pet treats, and more.

Moderate Barrier

A moderate level barrier protects against gases, moisture, aromas and sometimes UV light. The types of materials used for this moderate level barrier include the following:

• PVC
• PET

Polyethylene terephthalate or PET is lightweight, food safe, and is commonly used for thermoformed packaging for plastic water bottles, meat and cheese packaging, and microwave packaging.

Polyvinyl chloride or PVC is a more rigid plastic material and can break down from UV rays. This material is chemical resistant yet not as clear. Our soft vinyl products are made of this same material.

PET offers high clarity and an excellent print surface, making it a popular material for displaying decorative food products.

Popular products and uses: Our clear boxes and soft vinyl products are made with either PVC or PET material. For food packaging, PET is the best option. PVC is a better choice for products like office supplies, electronics, and short-term food storage. Soft vinyl products include bookmark sleeves, magnet sleeves, and luggage tags.

High Performing Barrier

High performing barriers are comprised of multilayers and protect against odors, freshness, moisture, gases, UV light, and visible light. The combined materials of high barriers include:

• PET in conjunction with another plastic PE or PP (OP, MOPP or CPP)
• PVDC Lamination: translucent, more affordable and usually laminated to PET to form KPET
• VMPET lamination: near opaque and affordable; 4 mil and over is considered smell proof.
• AL lamination: the near-perfect barrier; opaque and smell proof

On its own, PET is a strong plastic that offers an excellent oxygen barrier, durability, and heat resistance. When laminated onto certain plastics like PP or CPP, this blend of materials provides a strong UV and moisture barrier.

Polyvinylidene chloride PVDC is often used as a coating with other plastics (like PET). High gloss in appearance, PVDC offers excellent oxygen and moisture barrier properties, and is comparable to metallized films.

The highest barrier packaging is often a metallized laminate where the middle layer is VMPET or a thin layer of aluminum (Al) is placed on the surface of a plastic film.

VMPET is PET that has been metallized with aluminum and provides a high barrier to light and oxygen.

A layer of aluminum provides the best insulation against light and oxygen and is a near-perfect barrier. Our plant-based PLA stand up pouches are laminated with an ALOX (aluminum oxide) coating, allowing even our eco sustainable pouches to have outstanding high barrier properties.

Popular products and uses: Metallized stand up barrier pouches and heat seal bags, clear PLA-ALOX pouches, coffee bags, and child resistant bags for aromatic and flavorful food and dry goods. Products like jerky, seasoning packets, chocolate, coffee, bath salts, pet treats, and cannabis benefit from high barrier packaging.

Which barrier should you choose?

That all depends on what your needs are for your products. If you are packaging something non-perishable and don't need a lot of oxygen and moisture vapor protection, then you should stick with a basic-level barrier (though basic barriers are still acceptable for perishable products depending on how long you expect them to stay on the shelf). If you need to keep moisture out (or in on some product) and lock scents in/out, then the high-barrier is the best option.

Cost could also be a consideration here too. Typically the higher the barrier the more expensive the layers are in and of themselves (and you often have multiple layers on top of that). This means a higher cost. Don't overpay for a barrier that you will not need, but don't skimp on a barrier you might need to protect your product just to save on packaging costs. While cost is a consideration, it is just that, a consideration. You might choose a higher barrier for appearances or because you want a certain style. That's fine too..
