* Product Features:

The PVA coating provides the material with excellent barrier properties against gases such as oxygen, nitrogen, carbon dioxide, and volatile organic compounds (VOCs).

* Application:

It is used to improve the gas barrier properties of flexible packaging materials, and provides excellent protection for contents with high fat content, prone to oxidation, discoloration, and aroma escape, such as meat products, spices, small bread, pastries, dried fruits, and tea, thereby extending the product shelf life.

Tip:

Coating layer should be used in the middle layer, using solvent-free or dry composite, composite products can not be used for boiling, steaming.

The MOPE or we could say the MDOPE film, is a packaging material that requires further lamination process of single-component PE to

replace aluminum foil composite film or other multi-component composite materials, achieving packaging materials with greater recycling

value. It is mainly used as a face-stock for two-layer structures with heat-sealable PE materials or other three-layer composite structures.

In regards to this product, we need to understand your specific requirements, such as surface material thickness, packaging contents, bag

type, print pattern, oxygen barrier properties, drop impact requirements, downstream processing scenarios, etc.

In addition to MDOPE original film, we can also achieve high barrier or high-temperature sterilization performance through PVA coating.

Considering the compatibility issues between this product and downstream PE heat-sealing layer, we can also provide a three-layer composite

product of MDOPE surface material + PVA coating + PE heat-sealing film. Therefore, the quotation for this product requires that you provide

corresponding dimensions and technical requirements, downstream processing scenarios, and application scenarios.

If you do not much know about the points mentioned above, please consider 5 types of combinations (structure) as the base film for the downstream production at your site.

1) Single layer of MOPE:

- It requires that at least you have both your own laminating and heat sealing equipment.

2) 1 layer of MOPE + 1 layer of PE film (for heat sealing):

- You need have a heat-sealing equipment and it is adequate for packing dry fast food.

3) 1 layer MOPE laminated with 2 layer of PE (for heat sealing):

- The mechanical properties are higher than Option 2). for packing dry food. Unknown for beverage.

4) 1 layer of MOPE + PVA coating:

- VMDOPE, It requires that you have your own equipment to laminate the VMDOPE with PE heat-sealing film.

5) 1 layer of MOPE + PVA coating + PE heat sealing film:

- High end for both dry food and beverage. It requires you have a heat sealing equipment at least.
