Nowadays, stretch wrapping film is more and more commonly used in our lives. The quality of stretch wrapping film cannot be observed with the naked eye. A good stretch wrapping film has good tensile properties and is tear-resistant. As a disposable packaging product, stretch wrapping film must be of good quality when choosing, to ensure the packaging effect and protect the safety of the goods. Let’s take a look at the 5 reasons that depend on the quality of stretch film.
5 reasons that depend on the quality of stretch film.
Reason 1: Retraction stress of stretch film
Retraction stress, also known as force retention, refers to the degree of retention after the force exerted on the stretch film during the process of stretching the product;
Reason 2: The toughness of stretch film
Toughness refers to the comprehensive ability of stretch film to resist puncture and tear. The tear resistance only refers to the tear resistance of the film after being stretched and punctured;
Reason 3: Self-adhesiveness of stretch film
Stretch wrap films produce adhesion after contact with each other, which can make the packaged products firm and not loose during the process of stretching the products. Self-adhesion will be affected by many external variables;
Reason 4: The tensile force of stretch film
Stretch force refers to the tensile force that the stretch film converts into elastic stretching after being stretched. The increase in longitudinal stretch will eventually make the Dongguan stretch film thinner and shorten the width. This characteristic allows our stretch film to better protect and package products;
Reason Five: Strength of Stretch Stretch Film
The strength of stretch wrapping film includes two aspects: stretch rate and tensile force. It refers to the maximum stretch that can be exerted to maintain various necessary characteristics under certain conditions of use. Tensile strength varies with different uses. The greater the stretch, the less film is used and the lower the packaging cost.
