Plastic packaging film is commonly produced from polyethylene materials such as LDPE or LLDPE.
Its performance depends on film thickness, resin composition, processing conditions, and layer structure.
Key technical properties include tensile strength, elongation, puncture resistance, transparency, coefficient of friction, and heat-seal strength.
For printed or laminated applications, surface treatment and interlayer adhesion should also be evaluated.
The exact material grade and suitability for food contact must be confirmed through technical specifications and relevant test reports.
