Plastic/Resource Recycling Logo No. 1-7 (PET, HDPE, PVC, LDPE) fog brake? Understand the resource recovery sign in seconds
In fact, the plastic products we come into contact with every day have plastic recycling signs marked with No. 1 to No. 7, and these 7 numbers represent different plastic materials, and their characteristics, uses and heat resistance are also different. Start by understanding the plastic recycling logo to make your plastic recycling more secure!The plastic bottles and cans and plastic packaging handled in daily life are marked with plastic recycling logos, and the logo pattern is a triangle composed of three arrow cycles, and the triangle is marked with plastic sorting and recycling numbers 1 to 7, these 7 numbers represent different plastic materials, and their characteristics, uses and heat resistance are also different.
A picture to understand the 7 categories of recyclable plastics
Although these 7 types of plastics can be recycled, due to their low material and economic benefits, some items may not really be recycled. Therefore, if we want to protect the environment and love the earth, reducing the use of plastic is the key!
1、Plastic Recycling No.1 (PET)
Features: Transparent, lightweight, with a dot on the bottom of the bottle
Heat-resistant temperature: 60~85 °C, not heated, not recommended to be used many times
Common: Mineral water, soft drinks or tea bottles
Recycled PET is usually recycled into eco-friendly bags and eco-friendly clothing.
2、Plastic Recycling No. 2 (HDPE)
Features: Opaque or translucent, hard material
Heat-resistant temperature: 90~110 °C
Common: milk jugs, detergents
3、Plastic Recycling No.3 (PVC)
Features: Transparent, with a line on the bottom of the bottle
Heat-resistant temperature: 60~80 °C
Common: dishwashing detergent, mouthwash, egg cartons, raincoats, water hoses
Although PVC can be recycled, incineration produces dioxin, which pollutes the environment.
4、 Plastic Recycling No.4 (LDPE)
Features: Opaque or translucent
Heat-resistant temperature: 70~90 °C
Common: plastic bags, containers with squeezable bottles (e.g. ketchup)
Most of the plastic bags and plastic films are made of LDPE.
5、Plastic Recycling No. 5 (PP)
Features: Opaque or translucent, resistant to acids and alkalis, collisions, and chemicals
Heat-resistant temperature: 100~140 °C
Common: soy milk bottles, daily C juice, buckets, trash cans
6、Plastic Recycling No.6 (PS)
Features: Hard plastic plastic, easy to brittle when hit, divided into foamed and unfoamed. Unfoamed products are commonly found in Yakult and egg cartons, and foamed products are "Styrofoam".
Heat-resistant temperature: 70~90 °C
Common: Yakult, cup noodle bowl, hand-cranked drink cup
7、Plastic Recycling No.7 (OTHER)
Recyclable plastics in addition to the above six categories are classified in Category 7.
Heat-resistant temperature: PLA (plant-degradable plastic made from corn and beet extracts) 50 °C
Common: cutlery, drink cups
Plastic reduction cold knowledge|Biodegradable plastics, not completely decomposed!
In fact, the biodegradable plastics on the market may not be completely decomposable, and there are three main types:
1. Adding corn starch or calcium carbonate to traditional plastic materials cannot make the plastic disappear
2. Add photosensitizing accelerator, which can be cracked into fragments and powders in the natural environment, but not completely decomposed
3. Compostable plastic, which can be decomposed into organic matter, carbon dioxide and water under natural burial or composting
It is indeed very important to do a good job in general garbage, resource recycling and plastic recycling, but this way cannot completely prevent the earth's environment from being polluted by plastic, if we can start to reduce the use of plastic from the root, one person uses a little less, and the cumulative amount of plastic reduction per person will be very considerable.
