With excellent clarity, POF is a strong, biaxially oriented, heat shrinkable polyolefin film. Shrinkage is balanced and stable during packaging. It is soft, flexible and not embrittle in low temperature after shrink. It ensures your product to be better protected and does not give off any harmful gases. It is compatible with most shrink-wrap equipments, including semi-automatic and automatic system.

POF is an economical shrink film of wide application.

Available thickness: 12, 15, 19, 25 and 30 micron.

Trade value

•  Tend to suffer   low temperature, keep the same under negative 20°not becomes crisp and stiffening

•  exceptional thermal seal properties and high transparency and gloss ,soft and can improve the class of package.

•  Tend to suffer low temperature, not embrittle but stiffen in winter only if  add the thickness in case of breakage.

•  poor transparency and abrasiveness and optical effect is worse than POF

•  Will embrittle or break when under cold condition or in winter

•  ordinary transparency and gloss
