Title:
BAG BODY FOR MILK
Document Type and Number:
Japanese Patent JP3199958
Kind Code:
B2
Abstract:
PURPOSE: To contrive resource savings, a light weight, space savings, and an ease of recycling by a method wherein a bag body for milk is formed of a coextruded film of high-density polyethylene and low-density polyethylene comprising at least one high-density polyethylene layer and one low-density polyethylene layer, and the innermost layer is the low-density polyethylene layer of the coextruded film.
CONSTITUTION: A coextruded film of high-density polyethylene having a density of 0.94 or more and low-density polyethylene having a density less than 0.94 used for producing a bag body 20 for milk comprises at least one high-density polyethylene layer 20a and one low-density polyethylene layer 20b. The innermost layer of the milk bag body 20 is invariably the low-density polyethylene layer 20b. The low-density polyethylene layer 20b serves as the innermost layer of the milk bag body 20 for obtaining good heat-sealing properties. At least one high-density polyethylene layer 20a is required because the high-density polyethylene is superior in heat resistance and strength and is never affected by heat at the time of heat sealing.
