PP Polypropylene

 

PROPERTIES: PP is a hard and flexible material and with a waxy surface. PP softens at 140°C and offers high performance capabilities, particularly for food packaging. PP is recyclable but is not widely recycled in UK kerbside household collections.

 

CHARPAK PRODUCTS: Moulds and microwaveable products

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, PS is available in a variety of thickness of micron.  Whilst technically recyclable PS is not widely collected in UK household kerbside collections. 

 

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 do not manufacture packaging from PVC.

 

Having phased out PVC over a period of time, and made recommendations to clients who previously used this material, Charpak has been PVC free since 2018.

 

As a non-environmentally acceptable product packaging material Charpak do not advocate the use of PVC.  For alternative material the Charpak Technical Packaging Experts can make recommendations to switch to alternative packaging materials which provide the same technical and functional benefits.

OTHER Often Polycarbonate or ABS

 

PROPERTIES: All other resins that are not classified in the categories 1-6 are referred to in this category.  The Other classification of plastic resin includes multi materials such as laminates and coated materials such as flocked plastics.
