Plastic recycling sign and recycling solutions
2020-11-25
In our daily life, we often see some triangle and number marks printed on packages, but do you know what they represent respectively? And how to recycle them for re-use?
The recycling label for plastic products were established by the Plastics Industry Association in the United States. The identification code of plastic material is printed on the containers or packages, from No.1 to No.7, so people can Identify the plastic material of products simply by the recycling labels. Each plastic container has a small ID card - a triangle symbol, usually at the bottom of containers. There are 1-7 numbers in the triangle, and each number represents a kind of plastic containers. They are made of different materials and have different environments.
We ACERETECH is a creative company, focusing on the technology R&D of Plastic recycling and providing the equipment and solutions for plastics recycling, washing and re-granulation.
We have devoted ourselves to plastics recycling industries more than 20 years. And we are able to provide the customized plastics recycling solutions. If you have any questions about plastic recycling solutions, please feel free to contact us.
No.1
PET (polyethylene terephthalate), the containers made of this material, are a common plastic bottle for soft drinks, also known as "Baote bottle".
Common mineral water bottles, carbonated beverage bottles, etc. When PET is heated to 70 ℃, it is easy to deform and some harmful substances will be melted out. No. 1 plastic bottles may release carcinogen DEHP after 10 months of use; therefore, Do not put it in the sun in the car; , or pack them with alcohol, oil and other substances together.
To recycle PET bottles flakes, ACERETECH can offer you two options, one is ATE series twin screw extruder with lifting-type drying hopper, another one is ACS-H series compacting and pelletizing machine which is single screw.No.2
HDPE (high density polyethylene), opaque and feels like wax. Common are white medicine bottle, cleaning products, bath products. Do not use it as a water cup, or a storage container for other things. Do not recycle it If it has not fully cleaned yet.
To recycle HDPE bottle flakes, ACERETECH has three choices for you. One is ATE series twin screw extruder; the second one is ASE series single screw extruder. If you need a machine with a super-large capacity, then ACT series conical twin screw extruder is your top option. It is with large capacity, but low energy consumption.
No.3
PVC (polyvinyl chloride) is used to make water pipes, raincoats, schoolbags, building materials, plastic films, plastic boxes and other utensils.
The most common use cases are raincoat, building materials, plastic film, plastic box, etc. Because of its excellent plasticity and low price, it is widely used. But it can only heat to 81 ℃. It tend to produce bad substances at high temperature, so it is rarely used in food packaging. It is difficult to clean, easy to remain impurities and other toxic substances, so do not recycle. Do not buy this drink if the drink is loaded with PVC material.
To recycle this kind of PVC material, we suggest you use a shredder and crusher firstly.For hard PVC , use a pulverizer to make the PVC flakes into powder; for soft PVC, use a twin screw extruder to recycle it.
No.4
LDPE (low density polyethylene), plastic bags everywhere are mostly made of LDPE.
The common use cases are preservative film, plastic film, etc. High temperature will produce harmful , and toxic substances into the human body, may cause breast cancer, neonatal congenital defects and other diseases. Do not put the plastic film into the microwave oven.
To recycle LDPE film, ACERETECH recommends you our ACS-H compacting and pelletizing machine, which combines the function of crushing, compacting, plasticization and pelletizing to ONE STEP.
No.5
PP (polypropylene) is mainly used to make buckets, garbage cans, baskets, baskets and food containers for microwave ovens.
(The common use case are soymilk bottles, yoghurt bottles, juice drink bottles and microwave lunch boxes. It can be melted up to 167 ℃; it is the only plastic box that can be put into the microwave oven and be reused after careful cleaning. It should be noted that for some microwave oven lunch boxes, the box body is made of No. 5 PP, but the box cover is made of No. 4 PE. As PE cannot withstand high temperature, it can not be put into the microwave oven together with the box body.)
For recycle PP bottle flakes, ACERETECH has three choices for you. One is ATE series twin screw extruder; the second one is ASE series single screw extruder; If you need a machine with a super-large capacity, then ACT series conical twin screw extruder is your top option. It is with large capacity, but low energy consumption.
No.6
PS (polystyrene), due to its low water absorption, is mainly used to make building materials, toys, stationery, rollers, as well as cup boxes or disposable tableware for drinks in fast food shops.
(The common use cases are instant noodles in bowls and fast food boxes. In case chemical substances are released, do not put it into the microwave oven due to high temperature. Avoid using fast food boxes to pack hot food. Do not cook instant noodles in a microwave oven.)
For recycle PS materials bowls and fast food boxes, ACERETECH recommends you our ACS-H compacting and pelletizing machine, which combines the function of crushing, compacting, plasticization and pelletizing to ONE STEP.
No.7
Other. PC type, such as water bottle and baby’s bottle; PA type, namely nylon, is mostly used for fiber textile and some household appliances and other products. The toxic substance bisphenol A is easily released from PC at high temperature, which is harmful to human body. Do not heat it when using it. Do not directly exposure it to sunlight.)
For recycle PC /PA materials flakes, ACERETECH has two choices for you, one is ATE series twin screw extruder with lifting-type drying hopper, another one is ACS-H series compacting and pelletizing machine which is single screw.
