The hottest milk beverage paper packaging turned i

Milk beverage paper packaging is a 100% renewable resource. After effective waste classification and treatment, the packaging after consumption enters the recycling link, and then through various recycling treatment technologies, the small packaging can be transformed into recycled products such as recycled paper, Caile board, plastic particles and aluminum powder, which saves resources and protects the environment. At present, taking Tetra Pak packaging as an example, milk beverage paper packaging mainly adopts the following four technologies or processes for recycling:

first, hydraulic recycled pulp technology: separate the pulp in Tetra Pak packaging to produce recycled paper; The plastic and aluminum components in Tetra Pak packaging are extruded into granules, which become good raw materials for the production of plastic and aluminum products

II. Plastic wood technology: Tetra Pak packaging itself contains high-quality paper fibers and plastics, which are crushed and extruded to produce plastic wood products, such as indoor furniture, outdoor gardening facilities, industrial trays, etc., so as to make the best use of everything

III. Caile board process: Tetra Pak packaging is directly crushed and hot pressed to make Caile board. Caile board can be made into a variety of products, especially peel boxes, which are beautiful, durable and low-cost. The Expo Environmental Protection bench, which was brilliant at the 2010 Shanghai WorldExpo, is made of this material. The common faults and solutions of the spring change experimental machine are introduced

introduction to plastic wood technology

1 Process description

the plastic wood process is to crush the recycled milk beverage paper package into very small particles (~1 mm), and then plasticize the paper and melt the plastic under electric heating, so that the fiber and plastic in the milk beverage paper package can be firmly combined to form plastic wood particles

melt the plastic wood particles with the extruder, and then extrude them into new plastic wood materials in the corresponding mold according to the different shapes of the end customers' products, and then cut and assemble them into the final product

2. Product testing

the whole production process does not add additional adhesive, but uses the combination of paper plasticization and plastic melting in the package. According to the environmental protection monitoring department, plastic wood products are free of formaldehyde and other harmful substances, and plastic wood materials can be used in indoor decoration, outdoor materials and other fields

Caile board process introduction

1 Process description

Caile board process is to crush the recycled milk beverage paper package into very small particles (1~3 mm), and then melt the plastic under steam heating, and then firmly combine with the fiber in the milk beverage paper package. After hot pressing and cold pressing respectively, the final product is assembled according to the needs of customers

2. Product testing

no additional adhesives and other chemical raw materials are added in the whole production process. Steam heating is used to melt the plastic and firmly bond the fibers in the package. According to the environmental protection monitoring department, Caile board products are free of formaldehyde and other harmful substances, and Caile board materials can be used in indoor decoration, furniture processing, outdoor materials and other fields

introduction to hydraulic pulping process

1 Process description

the paper plastic separation of Tetra Pak packaging after consumption is realized by hydraulic pulper. The hydraulic pulping process mainly includes five main processes: pulping, slag removal, screening, washing, and pulping

2. Product detection

in the whole process of hydraulic pulping, no chemical raw materials and drugs are added, but the paper and plastic are separated by physical force. The separated aluminum-plastic sieve residue can be used as the raw material for aluminum-plastic separation production. The separated pulp of paper and plastic can be used as the raw material for the fixture used to clamp the experimental piece during the tensile test of household paper and packaging paper

introduction to aluminum-plastic separation process

1 Process description

aluminum plastic separation adopts a semi chemical and semi mechanical method to completely separate the aluminum film layer and the plastic film layer. The process flow mainly includes material preparation, reaction, sorting, purification, drying and packaging. The experimental machine is mainly used to measure the physical properties of materials or products

2 Product testing

after testing by relevant scientific research institutions, the separated aluminum powder and plastic film fully meet the quality requirements of industrial raw materials. Plastic film granulation can be widely used in the production of various non food containers, and aluminum powder grinding can be widely used in explosives, pesticides, paints, fireworks and firecrackers, as well as raw materials for the production of aluminum plastic plates and gifts
