[Instruction CD-ROM] D0624-1
【Abstracts】 The invention discloses a degradable environmental protection packaging material and a manufacturing method of the packaging material, which is formed by compounding a commonly used synthetic paper and a photo-oxygen-degradable polyethylene film through a water-based glue, and firstly, the weight content is 80-95. % of polyethylene and photo-oxygen-degradable green plastics with a weight content of 5 to 20% are mixed and melt-drawn into a photo-oxygen-degradable polyethylene film, and a water-based adhesive is evenly coated thereon to degrade the photo-oxygen after coating the aqueous glue. The ethylene film is continuously dried in at least two sections of the heating section, and the photo-oxidation-decomposed polyethylene film after the drying treatment is roll-pressed with the processing surface of a common synthetic paper to obtain an environmentally friendly packaging material. The finished packaging material can be cured to obtain the finished product. The environmental protection packaging material can be self-degraded in a natural environment, and causes less pollution to the environment. The preparation method is simple in operation, and the conditions and equipment requirements are very low, and it is suitable for industrial production.
