Matters Needing Attention When Purchasing Stretch Film

Stretch film is a very widely used packaging bag in modern industrial society. It is used for the packaging and transportation of various products. It also has high puncture resistance, good compressibility and certain compressive stress. Adhesion: Self-adhesion refers to the adhesion between the stretch films after contact. This feature can make the packaged items fasten without loosening during the stretching and winding process and after wrapping; self-adhesion is affected by various external identities. Such as humidity, dust and contaminants, this is also an important target for testing its benefits.

2. Toughness: Toughness refers to the comprehensive performance of the film against piercing and tearing. The risk level of the tear resistance level must be taken horizontally, that is, perpendicular to the mechanical operation direction, because tearing in this direction will loosen the package, and even if the longitudinal tear occurs, the package can still remain firm, so stretch The better the toughness of the film, the better the quality.

3. Stretching: Stretching is the ability of the stretched film to produce elastic elongation after being stretched. If the quality is good, the length will be extended after stretching, and within a certain limited range, it will not be broken; this is itself One of the characteristics of the product, with such a stretching function, can the items be packaged better.
