いた。However, linear low-density polyethylene (hereinafter L-L
Although DPE (referred to as DPE) has the above-mentioned excellent characteristics, compared to conventional high-pressure polyethylene, the temperature range for suitable heat sealing shifts to the high temperature side, and the melt tension is small, making it difficult to seal. There are drawbacks such as thin walls at both ends and insufficient sealing strength, and the market is currently not expanding as expected. For example, a single layer film made of L-LDPE, or
Extrusion coating and dry laminated films with an LDPE layer as a sealant layer have the disadvantage that the seal part opens when filling and sealing the contents for food packaging, etc., and there is a problem in preventing the seal part from opening. Bags made by filling and sealing the contents at a higher temperature have the disadvantage that both ends of the sealed part are thin, and the pressure of the contents is applied to the sealed part during transportation, causing the sealed ends to tear. There is a problem of material leakage. For this reason, when making bags by filling and sealing the contents in food packaging, etc., there is no opening in the sealed part and both ends of the sealed part do not become thin. An inkstone was requested.

Similarly, if the amount of high-pressure polyethylene added to 100 parts by weight of L-LDPE is less than 20 parts by weight, the low-temperature hot tack properties will not be improved, and if it exceeds 90 parts by weight, the characteristics of L-LDPH will not be improved. There is a problem that mechanical properties are impaired.
