Composite Laminated Film
Composite laminated film bonds print, barrier and heat seal layers into one structure — typically PET, aluminum foil or metallized film for the barrier, and PE or CPP for sealing. Produced in a D-class (100,000 class) cleanroom where printing, dry lamination and curing are managed as critical process steps, with solvent residue verified by gas chromatography. Supplied in roll form for sachet, strip pack and single-serve packaging across pharmaceutical, nutraceutical and cosmetic applications.

Questions
Frequently Asked Questions
Common questions about Composite Laminated Film — specifications, usage, and compliance
Each layer has one job. The print layer (PET or BOPP) carries artwork and adds stiffness. The barrier layer (aluminum foil, VMPET or VMCPP) blocks light, moisture and oxygen. The heat seal layer (PE or CPP) closes the pack. Reference densities are PET 1.40, AL 2.70, PE 0.92, CPP 0.90-0.91, VMPET 1.40 and BOPP 0.90-0.93 g/cm³.
Printing, dry lamination and curing are treated as critical process steps in a D-class (100,000 class) cleanroom, and finished film is tested for solvent residue by gas chromatography. Records can be supplied with the delivery.
Yes. Structures are designed from the product's sensitivities and the pack format, so layers, thickness and width are set per project rather than chosen from a fixed list.
Sachets, stick packs, strip packs and single-serve formats, plus printed wrappers where a metallized barrier layer is included.
Yes. Structures are produced to food-contact and pharmaceutical packaging requirements as applicable, with declarations issued for the structure supplied.

Recyclable Blister Packaging Under the EU PPWR: What to Specify Now
The EU Packaging and Packaging Waste Regulation pushes blister packs toward design-for-recycling, but recyclability depends on the material stream, the lidding and the collection scheme in each market. This note sets out how PVC, PVC/PVDC, PVC/APET laminates, APET and RPET sit against those requirements, and the specification points worth fixing before tooling and validation.
