BFI-1880 Metallocene (mPE) Properties:

Excellent permeability to Oxygen (used in packaging produce)
Superior optics
Excellent puncture resistance
Good tensile strength (at break)
Good sealability

Our BFI-1880 film has an outstanding balance of end-use performance (toughness, optics, sealability, hot tack and process ability).

(Originally published September 1998)

mPE and EVA films can be suitable alternatives to PVC film for some applications, and that the mPE film can provide a number of properties superior to those of the other film types, including tensile strength, tear resistance, resistance to blocking, and barriers to water vapor and ammonia. It was also shown that the use of mPE can allow for significantly thinner films than with EVA or PVC, without sacrificing performance.
