IMPROVED HEAT SEALING IRRADIATED FILM |
摘要 |
The invention relates to multi- layer polymeric structure, especially film, which can be produced by irradiation crosslinking of the polymer of a first layer without damage to the heat- sealability of a heat-sealable second layer. By including in the first layer a chemical component which when blended with a polymer in the melt form produces a material which crosslinks to a greater extent under irradiation than does the same polymer alone, it is possible to reduce the dosage of irradiation required for satisfactory cross-linking and thereby reduce or prevent damage to heat-sealing characteristics of the second layer. The laminate is useful for orientation to produce heat-shrink packaging material. |
