- GB 10457-1989.
Plastic cling wrap film for keeping fresh of food
1 Scope
This standard specifies the terms and definitions, product classification, identification, requirements, test methods, inspection rules and marking, packaging, transportation and storage of plastic cling wrap film for keeping fresh of food.
This standard applies to the plastic cling wrap film for keeping fresh of food which is produced using the polyethylene, polyvinyl chloride, polyvinylidene chloride and other resins as the main raw material through a single layer extrusion or multi-layer co-extrusion process (hereinafter referred to as wrap film).

3 Terms and definitions
The following terms and definitions apply to this standard.
3.1
Cling wrap film for keeping fresh of food
It refers to, for the purpose of packaging food, a type of film which has the self-adhesive function and food preservation or cleaning function.
3.2
Polyethylene cling wrap film for keeping fresh of food
It refers to the cling wrap film for keeping fresh of food which is produced using the polyethylene (PE) as raw material.
3.3
Polyvinylchloride cling wrap film for keeping fresh of food
It refers to the cling wrap film for keeping fresh of food which is produced using the polyvinyl chloride (PVC) as raw material.
3.4
Polyvinyl dichloride cling wrap film for keeping fresh of food
Moisture transmission deviation / % ?? 20
Self-cling (shear peeling strength) / (N/cm2) ??? 0.5
Open-wrapping The sample shall be totally opened in 5 s.
Anti-fogging
Under the test conditions, the surface of the
wrap film shall be free from water droplet
attachment OR otherwise there is only local
small droplet attachment. It is not allowed to
