  • Charpak mark all* manufactured products with the correct plastics recycling symbol to aid recycling (*with the exception of lids)
  • Charpak offer closed loop recycled materials – with 100% traceability of material. Charpak can control the product quality based on our clients’ requirement of plastics source
  • Charpak’s PET packaging contains 50% PCW (post consumer waste) and up to 40% PIW (post industrial waste).

 

Charpak manufacture packaging using PET, CPET, Bio-PET, PP, HIPS, Flocked materials and PVC. Charpak products are manufactured predominantly from clear and black rPET.

CHARPAK PRODUCTS: Moulds and microwaveable products

plastic interior packaging

PS Polystyrene

 

PROPERTIES: PS is lightweight packaging material and provides good water resistance and durability.  PS is hard, stiff, transparent and brittle. PS helps keep dry and wet food products fresher for longer minimising food waste.

 

Easily thermoformable into multiple shapes, and available in a variety of thickness of micron.  Recyclable

 

CHARPAK PRODUCTS: Tearable moulds, confectionery trays, and chocolate packaging

PVC Polyvinyl Chloride

 

PROPERTIES: PVC-P is plasticised PVC and is flexible, clear and elastic.  Charpak manufacture in PVC, though only manufacture when a client specifies PVC is required.
