Test items for stretch wrap film for transport packaging-TST

Wrapping film, also known as stretch film, is a new type of industrial packaging film products. It is characterized by light, soft and thin, good tensile properties, elongation properties and self-adhesive properties. Its application in transportation packaging is a packaging method that improves packaging efficiency and saves costs. In order to ensure the production quality of packaging stretch film, manufacturers need to produce according to certain standards.

We, CELL INSTRUMENTS, has presented below testers for stretch film testing.

Tensile force and elongation at break, according to ASTM D882

Samples are cut to a width of 15mm. The sample should be cut after unwinding roll for 1m, and cut evenly at approximately equal intervals along the length or width of the sample. Set the TST-01 tensile testing machine gauge length to 50mm, and the test speed is 250mm/min±25mm/min. There are two sets of vertical and horizontal sets, each set of samples shall not be less than 5, and the arithmetic mean value shall be taken, accurate to 0.1N.
