  Environmental Statement  
     
  Food contact approval and environmental effect of polythene film supplied by Williams Packaging Limited

The pallet stretchwrap films purchased by Williams Packaging are all made from blends and/or coextrusions of polyethylene or copolymers where ethylene is the major component. All the materials used in the manufacture of pallet stretchwrap film are approved for direct contact with food. However, since the films are not intended to come into direct contact with foodstuffs they are not specifically certified as being suitable for direct contact with food but suppliers are actively enforcing procedures in accordance with the BRC/IOP Technical Standard for Companies Manufacturing and Supplying Food Packaging Materials for Retailer Branded Products in conjunction with ADAS.

The films may contain a polymeric tackifier – polybutene – if produced by blown film technology process. The films do not contact PVC, phthalates or other property modifiers. The films do not contain the heavy metals lead, cadmium, mercury and hexavalent chromium in concentrations where the total concentration exceeds 100ppm by weight and therefore comply with the Packaging (Essential Requirements) Regulations (1998).

.The films do not contain the following chemicals:

 
 
  • Cadmium and cadmium compounds
  • PBB (polybromobiphenyl) category and BPDE (polybrominated biphenhyl ethers) category
  • Chlorinated paraffin (chlorine flame retarding material/pasticizers)
  • Polychlorinated biphenyl (PCB) category
  • Polychlorinated naphthalene category
  • Organic tin compounds (tributhyl tin category & triphenyl tin category)
  • Asbestos
  • Azo compounds
  • Ethylene oxide

 
  All the stretch films produced by our manufacturers are fully recyclable. Most of the stretch film that is produced contains a significant element of reprocessed in-plant process waste. Due to the problems of colour contamination and the high levels of stretch applied to the films we purchase there is no post-use waste currently used within the manufacturing process. Such material is however used for a wide variety of other applications – for example refuse sacks, construction film, temporary protective covering film, mulch film, ect.
