Abstract

The invention provides a polyethylene (PE) film and a preparation method thereof. The PE film sequentially comprises a composite layer, an intermediate layer and a heat-seal layer, wherein the composite layer comprises 25 to 40 weight percent of low-density PE, 25 to 40 weight percent of linear low-density PE and 33 to 45 weight percent of modified metallocene linear low-density PE; the intermediate layer comprises 25 to 50 weight percent of the low-density PE and 50 to 75 weight percent of the linear low-density PE; and the heat-seal layer comprises 28 to 35 weight percent of the low-density PE and 65 to 72 weight percent of the linear low-density PE. The invention also provides a cleaning solution packaging composite film and a cleaning solution packaging bag, wherein the cleaning solution packaging composite film is prepared from the PE film. Correspondingly, the invention also provides a preparation method of the cleaning solution packaging composite film which is prepared from the PE film. A product is packaged by the PE film provided by the invention, so the packaging bag has certain solvent resistance and excellent heat-seal performance, the relatively high sealing property and tensile strength of a material subjected to heat sealing are guaranteed, and the leakage resistance and falling resistance of the composite film which is prepared by the material are further improved.

Description

technical field

[0001] The invention relates to the field of washing product packaging, in particular to a polyethylene film and a preparation method thereof, a washing liquid packaging composite film and a preparation method thereof, and a washing liquid packaging bag. Background technique

[0002] In recent years, as people pay more and more attention to health and hygiene, the types of washing liquids have not been short-changed, and the demand is also increasing. Washing supplies have become a must-have for people's lives. Compared with solid washing liquid products, washing liquid has good water solubility, does not need artificial dissolution, and is more convenient to use, especially suitable for frequent washing needs of urban people. However, due to the high fluidity and certain chemical corrosion of the washing liquid, the washing liquid must be packaged before entering the market for sale.

[0003] Compared with the packaging of other products, washing liquid pac...
