Microwaveable Food Grade Transparent Retort Pouch Oxygen Barrier
Matepacking Ltd' retort pouches are constructed from varying grade
films which are laminated together. Material structure includes
high barrier aluminium material or microwaveable clear material,
could withstand temperatures ranging from 120℃ to 135℃ and provides
the moisture-proof, oxygen-proof, strength, toughness, puncture and
burst resistance that enable them to withstand the strenuous retort
1. Withstand temperatures max 135℃
2. Good looking with your logo
3. Easy to carry, store and transportation
4. Burst resistance and puncture resistance
5. Eco friendly FDA commitment materials.
6. Excellent moisture-proof and oxygen-proof.
7. Optional reclosable spout
8. Transparent window
As for Retort Pouch, the key point is Material + Lamination +
We only use RCPP from Japan, which can support maximum 135℃.
We have testing machine like attached photo.
We have workers with more than 15 years' experience in the retort
bag lamination and bag making.
And we'll do lamination testing and Tensile Strength testing during
production to ensure quality.
c. Printing Oils:
The oils are eco-friendly and support high temperature retorting.

1. We'll use transparent high barrier KPET+PA+RCPP for Vegetables,
Meat or Nuts.
2. The size and thickness will depends on the weight of your
vegetables or meat.
3. We only use KPET & RCPP from Japan, which can support max
135℃, and have strong barrier function against Oxygen and water.
4. KPET is PET with PVDC coating, which can realize Oxygent
Transmission less than 0.1cm3/m2.24h
Quality Control Processes
1. Cutting pouches into single small piece layer
2. Stripping small piece of pouch into single layer
3. Put layer into Tensile test instrument
4. Meanwhile,artificial olfactory test are in progress
5. Retort bags must put in Boiled Hot pot to cook
6. Pouches must pass QC report to get "Conformity" before shipment
Testing content and method
Total≤5mg/M²,Benzene can't be dedetected
Negative pressure sealing 0.07Mpa, 30s, Sealing position is
1m free-falling in 3 times,80kg pressure resistance in 60s,no leak
Boiling at 90 ℃,30mins,do not leak and damage
Stewing at 121℃,Stewing at 135℃,30mins, no leak no damage
