How to conduct resistance testing of stretch wrap film
Jan 20,2025
Stretch wrap film is mainly used for packaging goods, which is an outer layer protection application suitable for large goods packaging. Due to the relatively long product protection period, it has certain durability requirements in the production process. As long as the stretch wrap film with good tensile strength is packaged properly, the effect will be better and safer. If the durability of stretch wrap film is poor, the stretching effect will be greatly reduced. Therefore, when purchasing stretch wrapped protective film that has been stretched, we must first understand whether the resistance of the stretch wrap film during the stretching process is suitable for packaging goods. So, how to conduct conventional stretch wrap film resistance testing in production and life? Next, the editor will give you a specific introduction. The specific content is as follows:
When using stretch wrap film, there is often a problem of poor stretching, which is also a headache. Poor stretching can easily lead to dissatisfaction with its packaging, greatly reducing the main impact on surrounding packaging. Therefore, customers should pay attention to this when purchasing wrapped protective films that have already undergone stretching treatment.
If you want to measure and distinguish its tensile performance, first tear it appropriately along the longer side of the stretched winding film, and then tear it horizontally to see if the stretched winding film has a certain impact resistance. If the tensile resistance of the film is poor, it is easy to tear. If it is too thin, the tolerance will be greatly reduced and the tensile performance will be poor. Therefore, the editor reminds you not to blindly pursue cheapness when purchasing stretch wrap film.
Stretch wrap film is commonly used in industries such as packaging, papermaking, logistics, chemical, plastic raw materials, building materials, food, glass, etc. Good self adhesiveness, transparency, and high-end products. High strength, high elastic tension, suitable for any shape of product. It has excellent puncture and tear resistance, and can avoid damage to items during the binding process. It has good anti loosening, rainproof, dustproof, anti-theft and other effects.
We can start testing the resistance of stretch wrap film from the product itself. The quality will be reflected in the application process. Therefore, we must be cautious when choosing products.
There are many companies that mainly produce and sell stretch wrap film products nowadays, but as consumers, when looking for suitable production institutions to cooperate with, it is necessary to choose a production team with rich experience. Such manufacturers can not only continuously explore and develop in product production, but also form a production, sales, and service chain that integrates production, sales, and service for customers, and do a good job in product quality control for customers. Only companies like this can win the trust of customers and establish long-term friendly cooperative relationships with them.
