2, packaging reduction. In some developed countries, many supermarkets encourage consumers to use reusable nylon shopping bags instead of disposable plastic bags, minimize the materials used in packaging design, eliminate unnecessary packaging as much as possible, and advocate simple packaging to save resources.
3. Simplification of packaging materials. The materials used should be as simple as possible, and don't mix different materials, which is convenient for recycling.
4. The packaging design is detachable. Packages that need a composite structure should be designed as a detachable structure, which is convenient for recycling after disassembly.
5. Pay attention to the reuse of packaging materials. Adopt recyclable, reusable and recyclable packaging to improve the life cycle of packaging, thus reducing packaging waste.
6. Harmless packaging materials. The European packaging and packaging waste directive stipulates the content of heavy metals (lead, mercury and chromium, etc.). ), for example, the lead content is less than 100PPM. China should also legislate to prohibit or reduce the use of some packaging materials containing harmful components such as lead, mercury and tin, and stipulate the allowable content of heavy metals.
Extended data:
1, select recycled materials.
Choosing recycled materials can not only improve the utilization rate of packaging materials and reduce production costs, but also save a lot of energy, reduce the consumption of other resources and reduce environmental emissions.
2. Choose recyclable materials
Choosing packaging materials with good recycling performance is one of the effective ways to realize green packaging. Polystyrene (PET) is a kind of recyclable and clean high-quality plastic packaging, which is often used in beverage packaging. Procter & Gamble also uses it to package household cleaners.
Step 3 Choose degradable materials
Degradability means that non-recyclable packaging waste should be able to decompose, corrupt and return to nature or ecology within a certain period of time.
4. Try to use the same packaging materials.
Try to use the same packaging materials, and avoid using multi-layer packaging bodies made of different materials, so as to reduce the separation of packaging materials and improve the recycling performance of packaging materials.
