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

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.
