Product Features:

　　1. Wide temperature range. HDPE Film can be used not only for frozen food packaging, but also for packaging bags that need to withstand boiling sterilization (100 ° C boiling resistance).

　　2. Has higher mechanical strength. HDPE Film is the strongest one in polyethylene packaging Film, and its tensile strength can be more than twice that of LDPE packaging Film (20Mpa or more). Therefore, using HDPE as the packaging film can reduce the thickness and unit consumption. lower the cost. The physical mechanical properties of HDPE Film are shown in the following table (the thickness of HDPE Film listed is 25 microns)

　　3. Has excellent moisture resistance and good oil resistance. HDPE Film is the most water-soluble variety in commonly used packaging Film. Although its oil resistance is not as good as that of barrier films such as nylon, it is the best variety among polyethylene films.

　　4. Heat sealing is easy and can be repeated.

　　5. Excellent water resistance, moisture resistance and chemical resistance.

　　6. The transparency of HDPE packaging Film is significantly lower than that of LDPE packaging Film. The poor transparency of HDPE packaging Film affects its application in many packaging fields. However, when Film is required to be light-shielding (non-light-transmissive), less light-shielding agents (such as titanium dioxide, can be added to HDPE Film). Carbon black) to obtain translucent or opaque Film.

　　7. HDPE packaging Film has good rigidity and poor softness. Due to the poor flexibility, the film thickness is limited. The maximum thickness (limit value) of HDPE packaging Film is 0.10mm.

Product Uses:

　　The main uses of HDPE packaging Film are some molded processed products, including blow-molded films that are extruded, and also used in food packaging, grocery shopping bags, fertilizer liner films, bags, films for edible fungus packaging, and general industrial blown films Garbage bag. In addition, there is also a composite film, which can be used for food's anti-permeation and thermal insulation packaging film.
