Standards and methods for Selecting eco-friendly PVC bags
First, clarify the core standards for environmentally friendly PVC bags
Environmental friendliness of materials
Avoid harmful additives: Prioritize PVC bags that do not contain toxic plasticizers such as phthalates (like DEHP), as these substances may pose a threat to human health and the environment.
Recyclable or degradable: Although traditional PVC bags are not easy to degrade, some eco-friendly PVC bags can reduce environmental pollution to a certain extent by adding bio-based components or improving the formula. If complete environmental protection is pursued, PVC alternative materials (such as PLA, PBAT and other degradable plastics) can be considered.
Environmental protection certification: Check whether the product has passed international environmental protection certifications, such as the REACH certification of the European Union, the FDA food-grade certification of the United States, or the domestic GB/T 21661-2008 standard (for environmentally friendly plastic bags).
Environmental friendliness of the production process
Low energy consumption and low emissions: Choose manufacturers that adopt clean production processes to reduce energy consumption and pollutant emissions during the production process.
Wastewater and waste gas treatment: Find out whether the manufacturer has complete wastewater and waste gas treatment facilities to ensure that the production process meets environmental protection requirements.
Environmental protection treatment after use
Recyclability: Confirm whether PVC bags can be recycled and reused. Some eco-friendly PVC bags can be recycled through specific channels and made into recycled materials.
Degradation performance: If a product claims to be degradable, it is necessary to verify its degradation conditions and cycle to avoid being misled by false advertising.
Second, the specific methods for purchasing eco-friendly PVC bags
Appearance and feel inspection
Color and transparency: Eco-friendly PVC bags usually have uniform color, high transparency, and no impurities or spots. If the bag is cloudy in color or has an unpleasant smell, it may have been made of inferior materials or recycled materials.
Flexibility: High-quality and environmentally friendly PVC bags should have good flexibility and be not prone to cracking. Its flexibility can be tested by bending or folding.
Performance test
Load-bearing capacity: Select PVC bags of appropriate thickness based on usage requirements and test their load-bearing capacity through actual loading to avoid damage caused by overloading.
Sealing property: Check the sealing process of the bag to ensure good sealing and prevent the contents from leaking or getting damp. The sealing methods of high-frequency heat sealing or ultrasonic welding are usually more reliable.
Weather resistance: If the PVC bag is to be used outdoors, its resistance to ultraviolet rays and high and low temperatures should be tested to prevent aging or brittleness due to environmental factors.
Certification and marking verification
Environmental protection labels: Check whether the product is printed with environmental protection labels, such as recyclable labels, degradable labels, etc.
Test Report: Request the manufacturer to provide a third-party test report to verify whether the environmental protection performance and physical properties of the materials meet the standards.
Supplier Evaluation
Enterprise qualifications: Choose manufacturers with environmental protection production qualifications and a good reputation, and avoid purchasing from small workshops or unqualified suppliers.
After-sales service: Confirm whether the manufacturer provides environmental protection treatment suggestions or recycling services to ensure environmentally friendly disposal at the end of the product’s life cycle.
Third, alternative solutions to environmentally friendly PVC bags
If you still have doubts about the environmental friendliness of PVC materials, the following alternative solutions can be considered:
Biodegradable plastic bags: Bags made of materials such as PLA (polylactic acid) and PBAT (polyadipate/butylene terephthalate) can degrade relatively quickly in the natural environment.
Bio-based plastic bags: Made from natural polymer materials such as starch and cellulose, they have better environmental protection performance.
Paper packaging: For lightweight items, paper packaging is a more environmentally friendly choice.
Fourth, avoid common purchasing mistakes
Beware of “pseudo-environmental protection” propaganda: Some manufacturers may exaggerate the environmental performance of their products. It is necessary to verify through certification and test reports.
Do not overly pursue thickness: Environmental protection has no direct connection with thickness. A reasonable choice of thickness can meet the requirements and avoid resource waste.
Pay attention to the environmental friendliness throughout the entire life cycle: It is not only necessary to consider whether the material itself is environmentally friendly, but also to take into account the environmental friendliness of the production, use, recycling and other links.
