Overview of DIAMIRON™ MF Type P4
A polylactic acid (PLA) multi-layered film
PLA is a plant-derived plastic.
Composition
Features
1 The biomass plastic composite film's rigidity provides excellent curling properties.

| Content: | 40 grams of sliced ham |
|---|---|
| Cover material: | OPP (30 µm) / VMPET (12 µm) / EVA (40 µm) |
2 Comparable with existing films in pinhole resistance
We conducted a drop test with an actual package under severe conditions to observe the state of the package.
[Test description]
A cardboard box packed with 10 sets of three packages (each containing 80 grams of sliced ham) with a deep-drawing depth of 10 mm, was dropped from the height of 1.5 meters after 24-hour conservation at an atmospheric temperature of 5℃.

Notes on Type P4
- The PLA has weak heat resistance with a glass transition point (Tg) of 60℃. The sealing process may leave a rubber packing mark. (PETG has a Tg point of 80℃.)
- Folding of the film at an acute angle may leave a mark but it has no impact on the film quality.
- You may notice a smell specific to PLA at the time of deep-draw packaging (sealing).
- At ambient temperatures, very little hydrolysis occurs. However, we use the precaution of delivering the film in a moisture-proof package (moisture-proof paper pipe or aluminum package).
- Store the film in a cool dark place and avoid leaving it unpackaged to prevent moisture absorption.
- The film quality is guaranteed for a period of six months after shipment.
