Abstract

The invention relates to packaging composite films, in particular to a detergent packaging composite film and a preparation method thereof. The detergent packaging composite film sequentially comprises a first nylon layer, a first bonding layer, a first base material layer, a second bonding layer, a second nylon layer, a third bonding layer, a second base material layer, a third base material layer and a fourth base material layer, the first nylon layer and the second nylon layer are made of a material comprising PA, the first bonding layer, the second bonding layer and the third bonding layer are made of a material comprising a mixture of TIE and PE, the first base material layer and the second base material layer are made of a material comprising a mixture of HDPE and LLDPE, and the third base material layer and the fourth base material layer are made of a mixture of HDPE, LLDPE and MPE. By pretreating raw materials and compositing multiple layers of films, corrosion resistance and aging resistance of the materials are improved substantially, and each index is much higher than national standards.

Description

technical field [0001] The invention relates to a packaging composite film, in particular to a cleaning agent packaging composite film and a preparation method thereof. Background technique [0002] Polyethylene is the simplest polymer organic compound and one of the most widely used polymer materials in the world today. Polyethylene is polymerized from ethylene and can be made into a wide variety of applications. Polyethylene is also the main material for packaging materials. As a packaging material, it has the following advantages: polyethylene is resistant to various organic solvents and various acids and alkalis, but it is not resistant to oxidative acids, such as nitric acid; crystallized material, which absorbs little moisture and does not need to be fully dried. But there are also some disadvantages, such as large shrinkage range and shrinkage value, obvious directionality, and easy deformation and warping. [0003] Polyethylene can be divided into high-density pol...
