One Side Corona Treated Cigarette Shrink BOPP Film For FMCG Product Package
Introduction:
Biaxially oriented polypropylene (BOPP) film is film stretched in both machine and transverse directions, producing molecular chain orientation in two directions. BOPP film is produced by a tubular process, in which a tubular bubble is inflated, or a tenter frame process, in which a thick extruded sheet is heated to its softening point (not to the melting point) and is mechanically stretched by 300–400%. Stretching in the tenter frame process is usually 4.5:1 in the machine direction and 8.0:1 in the transverse direction, although these ratios are fully adjustable. It is a widely used process, more common than the tubular process, and a glossy, transparent film is produced. Biaxial orientation results in increased toughness, increased stiffness, enhanced clarity, improved oil and grease resistance, and enhanced barrier properties to water vapor and oxygen.
Its comprehensive performance is superior to moisture-proof cellophane, polyethylene (PE) film, and PET film. BOPP film also has excellent printing effects. The representative physical property data are: turbidity <1.5%; gloss> 85%; tensile strength (longitudinal / transverse)> 120 / 200MPa; elongation at break (longitudinal / transverse) <180% / 65%; elastic modulus It is 1700 ～ 2500Mpa; the embrittlement temperature is -50 ° C.
