Oxygen Barrier Packaging for Prepared Foods is ideal for semi-finished and finished prepared dish packaging. The Freshness Lock Prepared Produce packaging film maintains reduced food spoilage. Locks in flavour and freshness while keeping the pouch looking transparent and non-yellowing for a more appealing retail appearance with Premium Ready to Cook packaging BOPA film.
This Ultra High Oxygen Barrier BOPA Film for Prepared Foods has high composite strength that is not easily torn like traditional aluminium foil packaging in the market for High Barrier Film for Ready to Eat Meals. This Premium Ready to Cook packaging BOPA film also has a wide temperature range from freezer safe to microwavable, for the Oxygen Barrier Packaging for Prepared Foods. Another advantage of this Ultra High Oxygen Barrier BOPA Film for Prepared Foods is that it is metal detectable for extra safety in the production of High Barrier Film for Ready to Eat Meals. The flexible PA material of this Freshness Lock Prepared Produce packaging film also allows for more shipping space for transportation.
High temperature stability of Ultra High Oxygen Barrier BOPA Film for Prepared Foods enables the film to be filled at 85-100 degrees centigrade filling temperatures. This High Barrier Film for Ready to Eat Meals protects the flavour and taste of each bite of ready to eat food by preventing oxidation. Being used as an oxygen barrier packaging for Prepared Foods or Premium Ready to Cook packaging, BOPA film gives transparency to inspect the product through. With a huge production capacity of 150,000 tons yearly, the availability of Ultra High Oxygen Barrier BOPA Film for Prepared Foods is all set to fulfil the world’s requirement for Freshness Lock Prepared Produce packaging film.

Reasons you need EHAp®, EHAr®- Ultra High Oxygen Barrier BOPA Film for Prepared Foods/ Ready-to-Eat/ Ready-to-Cook/ Meal Kits/ Fresh-Cut:

Food Safety & Inspection: Detectable for preventing prepared food from failing the metal detection; Translucent for inspecting the product
Microwaving & Cooking: Microwaveable and heat-resistant up to 85-100 fillings in the pouch for direct heating
High Performance: Higher composite strength without the risk of the pouch being torn, tear resistant like a foil pouch; Freezer resistant for maintaining the good condition of the pouch during cold chain transportation
Preservation: OTR (Oxygen Transmission Rate) < 2 cc/m² day·atm to prevent oxidation and to preserve the food fresh by slowing down the oxidation
Logistics Cost Reduction: Using the BOPA film; BOPA is a flexible packaging material, and this reduces the transportation cost compared to rigid packaging.

EHAp®, EHAr®-Ultra High Oxygen Barrier BOPA Film for Prepared Foods:
Sous-vide gourmet entrees (meats & fish): It is an ideal material for the increasingly popular sous-vide processing and packaging because it can handle continuous water temperatures of up to 212°F, while the Biaxial Orientation gives the pouch the puncture resistance it needs to handle bone-in meats. It also offers an ultra-high oxygen barrier (OTR 2) that prevents oxidation of the delicate animal fats that would otherwise ruin the chef-prepared flavour.
Ready-to-Eat (RTE) pasta and lasagna: These kinds of prepared pastas often have sauces and oils that can cause chemical migration in standard plastics. The PA6 + EVOH structure resists that and offers a "Freshness Lock" that keeps sauces from drying out and pastas from becoming rubbery.
Microwaveable vegetable steam-bags: In the case of prepared produce, the film can handle the broad temperature range that moves from refrigerated to high-heat steaming without the release of unpleasant odours or discolouration. The film is transparent and non-yellowing, so consumers can see the bright, fresh colours of the vegetables both before and after cooking.
Plant-based meat alternatives: Plant-based alternatives are prone to oxidation, which can result in unsightly discolouration. The ultra-high oxygen barrier effectively resists oxidation to ensure the product retains its "meat-like" colour and flavour consistency throughout its shelf life.
Prepared savoury stews and curries: Many of these items are hot-filled at 185°F–212°F. The film's high-temperature resistance and high composite strength give the bag the strength it needs to resist deformation and "foil-tearing" during the filling and cooling process.

EHAp®, EHAr®- Ultra High Oxygen Barrier BOPA Film for Non-edible Applications:
Medical Saline Bags: Requires high strength and heat stability for sterilisation.
Industrial Chemical Pastes: Keep prepared chemical compounds (which may be unstable in air) from coming into contact with oxygen.
High-Grade Balloons: The high barrier properties are ideal for holding in helium or other gases.
Cosmetic Clay Masks: Keep moisture and oxidation from entering "ready-to-use" facial scrubs.

Everything You Need to Know About Ultra High Oxygen Barrier BOPA Film for Prepared Foods
Why is this film superior to aluminium foil for ready-to-eat meals?
Conventional foil tears easily when flexed, cracking in transit and destroying the vacuum packaging seal. This High Barrier Film for Prepared Meals has high composite strength that does not crack like foil but is clear and microwaveable. That makes Oxygen Barrier Packaging for Prepared Foods easier to use.
What about "Ready to Cook" dishes with marinades?
Marinades are acidic or oily. The PA6 + EVOH used in this Premium Ready to Cook packaging BOPA film provides a strong chemical barrier, which will not break down. It preserves the taste and smell of the marinade and keeps the meat or vegetables “Fresh-locked” and fully seasoned, until cooking.
Does the film hold up if the prepared meal is frozen?
Yes. The film has a high degree of temperature flexibility and is known for its freeze stability. This means that the Oxygen Barrier Packaging for Prepared Foods does not get brittle or crack when frozen, and the Biaxial Orientation strength is retained from the distribution centre to the customer’s freezer.
