Food packaging laminated film is one kind of plastic composite material.
Generally, it is laminated by below materials
Lamination Structure Of Food Packaging Laminated Film
- PET/VMPET/PE
- PET/PE
- BOPP/VMPET/PE
- BOPP/PE/MPET/PE/CPE
- NY/AL/NY/PE
- PA/PE
layer | Material | feature |
Out layer | PET/NY/ONY/PA /OPP | Printable/heat-resistance |
Mid-layer | AL/VMPET/PET/NY | Enhance property |
Inside layer | PE | Non-toxic/smelless/low-melt/oil&water proof |
Total thickness ≤250um
Explanatory Note:
PET: is the most common thermoplastic polymer resin of the polyester family and is used in fibres for clothing, containers for liquids and foods, thermoforming for manufacturing, and in combination with glass fibre for engineering resins.
VMPET/MPET: Vacuum Metallized PET
PE: Chemical formula (C2H4). Usually a mixture of similar polymers of ethylene
CPE: Chlorinated Polyethylene Chemical formula (CH2-CHCl-CH2-CH2)
NY/ONY/PA(Nylon): is a generic designation for a family of synthetic polymers, based on aliphatic or semi-aromatic polyamides. Nylon is a thermoplastic silky material that can be melt-processed into fibers, films or shapes
BOPP: A common application for polypropylene is as biaxially oriented polypropylene. BOPP sheets are used to make a wide variety of materials including clear bags. When polypropylene is biaxially oriented, it becomes crystal clear and serves as an excellent packaging material for artistic and retail products.
