Commonly used for beverage bottles and mineral water bottles. Heat resistance is 70°C, and it can deform when containing hot liquids or when heated, potentially releasing harmful substances. Some people reuse mineral water bottles for drinks or tea, which is unhealthy.

Commonly used for cooking oil, shower gel, and detergent bottles, with a waxy feel. These can be reused for other products after thorough cleaning. Without proper cleaning, bacteria can easily grow.

Due to its low cost, PVC is widely used in products like pipes and raincoats. However, it has poor heat resistance, and toxic substances can leach out when exposed to high temperatures and oils, so it’s rarely used for food packaging. If used, please avoid heating.

Used for plastic wrap, bags, etc. It melts at temperatures above 110°C, and oils can cause toxic substances to leach out from plastic wrap. Therefore, plastic wrap should not be used in ovens.

Often used for soy milk bottles, yogurt bottles, and juice bottles. It can withstand temperatures up to 167°C and is the only plastic container that can be safely used in microwave ovens. It can be reused repeatedly after cleaning.

Used to make baby bottles, travel mugs, etc., and is a controversial plastic material. Theoretically, if completely transformed during manufacturing, these plastic products won’t release harmful substances. However, if transformation is incomplete, harmful substances may be released when heated. Therefore, please do not heat or expose to direct sunlight when using.

Used for shipping boxes and packaging boxes, made of multiple layers of cardboard with a wavy corrugated layer, providing a sturdy structure with cushioning properties.

When recycling, separate plastic windows and metal decorations. Can be made into new paper products after recycling, though fiber quality may decrease.

Applicable to regular paper such as printing paper, envelopes, magazines, and books. Can be recycled multiple times, saving water and energy with each recycling. Avoid oil stains and food contamination when recycling. Colored printed paper, thermal paper, and specially coated paper may contain chemicals affecting recycling. Recommended to be collected separately from other types of paper.
