LDPE (Low-Density Polyethylene) is a type of plastic commonly used for shrink films. Upon heating, the thickness of the LDPE shrinkage film will shrink, which is strongly proportional to the coating thickness. It is widely used for various packaging materials to provide protection, tamper resistance and professional appearance.
The softening process is due to the nature of LDPE. LDPE is a thermoplastic polymer, which means it is soft and melt able when heated above its glass transition temperature. When the film is exposed to heat, the polymer chains in the LDPE begin to move rapidly, causing the material to shrink and form around the coating
LDPE shrink film is widely used in packaging applications, such as joinery, packaging, protecting products during transportation and is commonly used in industries such as food packaging , electronics, and retail.
It is important to note that the shrinkage process must be done at a controlled temperature to avoid damaging the material or posing a safety hazard. Industrial heating methods or mechanical packaging are often used to achieve this to ensure uniform and consistent contraction.
sure! As mentioned earlier, LDPE shrink film is widely used in various industries for packaging and protection. Here are some additional details about its properties, functionality and usability considerations.
Characteristics of LDPE Shrink Film:
Transparency: LDPE shrinkage films tend to be transparent, allowing the packaging to be seen, which is useful for retail displays.
Durability: LDPE is known for its durability and flexibility, offers excellent resistance to tears and abrasions, and ensures that packaging will remain well protected if in transit
