If you want to maximize your product’s shelf life, you should look at EVOH liners. BN PACK knows that the right bag in box liner can keep your food or beverage fresh for longer. Your choice of packaging affects how well your product stays protected from air and moisture. Every product needs a barrier liner that fits its unique needs. Think about what matters most for your product as you read.
Barrier Liners & Shelf Life
Oxygen & Moisture Impact
You must keep oxygen and moisture away from your products. These two things make food and drinks go bad. Oxygen can get inside the package and cause oxidation. Oxidation changes how food tastes, looks, and smells. Moisture can let mold and bacteria grow. This can make food unsafe to eat.
Here is a simple table that shows how oxygen and moisture affect shelf life in food and beverage applications:
Aspect | Description |
|---|---|
Oxygen Absorbers | Remove oxygen to stop spoilage and keep products fresh |
Moisture Barrier Properties | Block moisture to prevent mold and decay |
Impact on Shelf Life | Control of oxygen and moisture is key for keeping food and beverage quality |
You should pick packaging that keeps out both oxygen and moisture. This is very important for food and drinks that need to last a long time.
How Barrier Liners Work
Barrier liners use special layers to stop oxygen and moisture. Each layer has its own job. The inner barrier layer keeps out gas and moisture. The outer polyethylene layer makes the package strong and helps seal it. Having many layers makes the barrier even better.
Here is how the layers work together in packaging:
Layer Type | Function |
|---|---|
Inner Barrier Layer | Prevents gas and moisture permeation |
Outer Polyethylene Layer | Provides strength and sealing |
Multi-layer Structure | Enhances overall barrier properties |
These liners use materials like polypropylene copolymer, ethylene vinyl alcohol, and anhydride-modified polypropylene resin. Mixing these materials makes a strong barrier against moisture. This helps keep food and drinks fresh and safe.
Barrier liners do more than just block oxygen and moisture. They help keep flavors and smells inside the package. They also protect against acids and other things that can hurt your product. The seal must be strong. Even the best liner will not work if the seal is weak.
BN PACK makes high-barrier packaging to protect your products. You get liners that help your food and drinks last longer. BN PACK’s bag in box packaging uses these ideas to help keep your products safe and fresh.
EVOH vs. Metallized PET: Barrier Comparison
EVOH Properties & Uses
You want packaging that keeps products fresh longer. EVOH stops oxygen from getting in very well. This material is a special kind of plastic. It blocks oxygen better than other plastics like PA and PET. EVOH has hydroxyl groups in its chemical makeup. These groups help EVOH work with metal layers and make the barrier stronger.
EVOH liners are good for food packaging. You can use them for things that spoil fast, like juice or milk. EVOH keeps oxygen out, so food stays safe and tasty. Even if you squeeze or move the bag, EVOH still works well. You can use EVOH films instead of foil or shiny laminations.
BN PACK uses EVOH in bag in box packaging. This helps your products last longer. EVOH liners protect from oxygen and light. They also keep out gases like nitrogen and carbon dioxide. Your drinks, chemicals, and medicines stay safe.
Here is a table that shows how EVOH works in bag in box packaging:
Feature | Description |
|---|---|
Core Layer | EVOH lets very little oxygen through, making a strong barrier. |
Structural Layers | PA and PE layers make the bag tough and keep out moisture. |
Shelf Life | EVOH bags help food last longer in the fridge or freezer. |
You can trust EVOH to keep products safe when stored or shipped. EVOH liners help you waste less and keep customers happy.
High-barrier FIBC liner bags are made for packing sensitive goods.
They stop oxygen and moisture, keeping products safe and good.
Products last longer in storage and shipping.
They block gases like oxygen, nitrogen, carbon dioxide, and helium.
Very little oxygen gets through, so food and medicine stay good.
They protect drinks and chemicals from oxygen and light.
Metallized PET Features
You might want packaging that protects and looks nice. Metallized PET, or VMpet, gives strong protection and a shiny look. VMpet uses a thin aluminum layer on PET film. This layer blocks oxygen and water vapor. VMpet is used for bag in box packaging, like for wine.
VMpet sticks well because the aluminum bonds to the PET film. This makes the barrier strong. VMpet does not crack as easily as aluminum foil. You can process VMpet without losing its barrier power. VMpet meets food safety rules, so you can use it for food and drinks.
BN PACK uses VMpet in bag in box packaging. This helps keep flavor and freshness. VMpet is good for things that need chemical resistance, like alcohol wipes. You can pick VMpet in different thicknesses, like 12 microns.
Here is a table that shows VMpet features in bag in box packaging:
Feature | Description |
|---|---|
Metal Adhesion | 850 g/25 mm, so the layers stick together well. |
Barrier Properties | Blocks oxygen and water vapor, keeping flavor and freshness. |
Flex Crack Resistance | Better than aluminum foil, so it lasts longer. |
Processability | Easy to use without losing protection. |
Compliance | Meets food safety rules in the US and Europe. |
Application Suitability | Great for bag in box, especially for wine and hot fill. |
Chemical Resistance | Good for things that need chemical protection, like alcohol wipes. |
Thickness | Comes in 12 micron thickness. |
VMpet is a cheap way to protect products. You get strong protection and a package that looks good.
OTR & WVTR Data Insights
You need to know how well each liner blocks oxygen and moisture. Oxygen transmission rate (OTR) and water vapor transmission rate (WVTR) show how good the barrier is. Lower numbers mean better protection.
Here is a table comparing EVOH and VMpet:
Polymer | WVTR (g−2 per day) (@ 37.8–40°C) | OTR (cm3(STP)−2 per day) (@ 20–23°C) |
|---|---|---|
EVOH (ethylene vinyl alcohol) | 1.4 – 8.0 | 0.005 – 0.12 |
EVOH has a very low OTR. This means it blocks oxygen better than VMpet and PET. VMpet also blocks water vapor well. The aluminum layer in VMpet helps its barrier, but EVOH is best for products that need to stay away from oxygen.
Here is a table that shows how the chemical structure affects barrier properties:
Material | Barrier Property Description |
|---|---|
EVOH | EVOH blocks oxygen well because it likes water and has hydroxyl groups that help with metal layers. |
Metallized PET | The barrier depends on the PET surface and how it works with the aluminum layer. |
EVOH’s special groups make it great for blocking oxygen. VMpet uses the aluminum layer and PET surface to protect.
EVOH is a special plastic that blocks oxygen much better than other plastics.
EVOH’s chemical resistance stops swelling and keeps the barrier strong.
Experts say EVOH is great for blocking oxygen. VMpet and PET block oxygen okay and cost less. You should pick based on your product and how long you want it to last.
BN PACK uses both EVOH and VMpet in bag in box packaging. You get choices that fit your needs. BN PACK helps you pick the best liner for your product’s shelf life and quality.
Choosing the Right Bag in Box Liner
Product Type & Shelf Life
You want your product to stay fresh for a long time. The bag in box liner you pick is very important. If you pack food or drink concentrates, you need a liner that fits your product’s needs. Some things spoil fast, but others last longer. You must think about how much air and water your product can take. EVOH liners are good for products that need to last longer. Metallized PET liners also protect food and drinks, but EVOH blocks oxygen better.
You should check how your product reacts to air and light. If you pack sensitive foods, like juice or milk, you need a liner that blocks oxygen and keeps it fresh. For drinks like wine or syrup, you want a liner that keeps flavor and freshness. BN PACK has bag in box packaging with liners you can choose, so you get what your product needs.
Tip: Always think about how long you want your product to last before you pick a liner.
Food, Beverage & Industrial Needs
You must know what you are packing. Food, drinks, and industrial products all need different liners. If you pack sour foods, like tomato paste or citrus, you need a liner that resists acid. For drinks like soda or juice, you want a liner that keeps out air and water. Industrial products, like chemicals or oils, need liners that resist strong chemicals.
BN PACK’s bag in box packaging works for many industries. You can pick liners for food, drinks, or industrial products. BN PACK helps you choose the right liner for your product’s shelf life and safety. You get packaging that meets food safety rules and keeps your product fresh.

Regulatory approval | FDA’s Food Contact Notifications system checks if a plastic is safe for food. |
Product pH, Oil & Storage
You need to know your product’s pH and oil level. These things help you pick the best liner. If you pack sour foods, like citrus or tomatoes, you need a liner that resists acid. If you pack oily products, you need a liner that resists oil. If the liner does not match your product’s pH, it can spoil or break.
Here is a table that shows which liners work for high acid or oil:
Liner Type | Application Description | Key Features |
|---|---|---|
Nitrile | Good for oil and gas because it resists oil. | Works well for hydrocarbon content above 200 ppm. |
Plastisol | Resists acid and works for high heat. | Makes an airtight seal when heated and cooled. |
HDPE | Used in mining and oil for chemical resistance. | Strong and resists acids. |
You should also think about how you will store your product. If you store food or drinks for a long time, you need a liner that keeps out air and water. Sour drinks need liners that resist chemicals to stop rust and taste changes. Non-sour drinks give you more choices, but you still need to check if they last long.
Note: Always match the liner to your product’s pH and oil level for the best shelf life.
Cost & Sustainability Factors
You want packaging that fits your budget and helps the planet. EVOH liners give strong protection, but they use many materials, so recycling is hard. Metallized PET liners are easier to recycle and are better for the environment.
