Low-Density Polyethylene: (LDPE Film Physical Properties)

This term is generally considered to include polyethylene's ranging in density from about 0.915 to 0.925. In low density polyethylene's, the ethylene monomeric units are linked in random fashion, with the main chains having long and short side branches. This branching prevents the formation of a closely knit pattern, resulting in material that is relatively soft, flexible and tough, and which will withstand moderate heat.

LDPE: Thickness of 0.001" to 0.030" made to your specifications:
BFI-NA345 is a series of homopolymer resins that combine premium clarity with strength and stiffness. In addition, BFI-NA345 exhibits good impact strength film. BFI-NA345 is recommended for textile packaging, light produce, bread bags and other thin packaging films enhanced by clarity and sparkle. The optical values of BFI-NA345 are excellent in thin gauge when produced with Cast Process. This fact leads to important cost savings. Film can be drawn down to a minimum gauge consistent with required physical properties, with the assurance that optical properties will not suffer, but improve.

FDA Compliance: BFI-NA345 film meets the requirements of the Food and Drug Administration, regulation 21 CFR177.1520. This regulation allows the use of this olefin polymer in "...articles or components of articles intended for use in contact with food." Specific limitations or conditions of use may apply.

LDPE is soft, low barrier, good clarity film. It is also the least expensive of all polymer packaging films. It is possible to alter basic properties of LDPE film by blending other polymers and/or additives, like EVA, LLDPE, Color Pigments, Black Carbon etc. to meet your specific application.

Very flexible, natural milky color, translucent with high impact strength. Excellent for mild and strong buffers, good chemical resistance. Good water vapor and alcohol barrier properties. Poor gas barrier, sterilizable with EtO or gamma radiation. Good stress crack and impact resistance.
