Product Features

The POF film (polyolefin shrink film) SURMO SL is characterized by its low shrink force and low shrink temperature. For thin items that distort easily and require a low shrink film. Another application of this film is for heat sensitive products such as yogurts, chocolates, candies, electronics, etc. It has a higher shrink rate making it a good candidate for odd shaped items and its wide operating window works well on a wide range of shrink machines.

The film is categorized as LDPE, which can be fully recycled and reused (SPI code 04). SURMO SL can be printed for the brand and meets the requirements related to direct contact with food (except when used to package food while it is cooking). The SURMO SL can be used for pre-punching or custom punching, simplifying machine setup and increasing packaging efficiency.

Product Advantages

Thin & Tough
Uniform thickness, good moisture resistance, and soft texture. High tensile strength, tear resistance, and over 60% shrinking ratio. Due to the presence of LLDPE, the friction resistance is better.
Cold Resistance
Not brittle, and not easy to break, even under -50℃ temperature. Can be used for frozen food packaging. After shrink wrapping, the packaged material can be stored frozen for a long time.
Dust Proof
When exposed to a temperature range, of 110℃~140℃, the film shrinks and then forms the shape of an object that packs it. It generates a perfect barrier to protect the object from outer contaminations.
Soft Surface
After heat shrinking, the film leaves soft corners of the packs. Will not hurt hands when touching the packs. The film surface is also resistant to friction.

POF Film Applications

POF film (polyolefin shrink film) is an excellent and easy-to-use multilayer packaging film. It has the characteristics of being non-toxic, environmentally friendly, transparent, heat sealable, and high heat shrinkage rate. Its excellent performance is far superior to simple polyethylene (PE) film and polypropylene (PP) film, and its special superior performance has been widely applied. This film is applicable to a variety of packaging, including food, beverages, frozen products, medicines, daily necessities, textiles, toys, stationery, discs, cosmetics, etc.
