Wuhan Handern Packaging Materials
The repeated recycling and recycling of packaging materials is the most practical and feasible step for the development of green packaging materials, and is one of the most active waste recycling methods to protect the environment and promote the recycling of packaging materials. In foreign countries, PET beverage bottles and PC milk bottles can be reused more than 20 times. Examples of reusable films are the sealing film discussed in section 2.1.3.7, which can be used repeatedly. Medication bags for outpatient seals in hospitals are fine. The recycling of general plastic packaging waste includes combustion method, landfill method and recycling. More requirements are still recycling, and landfills should be reduced to zero. Self-disposal and recycling of plastic film is more difficult than ordinary rigid plastics, and the methods currently used are as follows: www.handern.com non-woven equipment(1) The thick film is attached with a recycling mark to facilitate recycling and reuse, such as general PE heavy packaging film and thicker film. When printing the packaging bag, the recycling mark is also printed to facilitate recycling. In order to facilitate the recycling of plastic waste, advanced countries have formulated identification marks, and my country has also formulated standards for plastic recycling identification marks. It may be difficult to implement the recycling mark for light packaging films with 90% T-days. However, as long as you persist and take effective measures, it should be better than burning or landfilling. To some extent, it is more advantageous than using degradable plastics. www.handern.com Non-woven equipment
(2) The factory self-recycling of scraps and scraps in the factory product waste, its source is clear, and the classification and quantity of materials are easy to grasp. Therefore, it is the most effective method to recycle thoroughly in the factory, and use waste from each process to form a closed system for regeneration. For example, the trimming waste during film production is crushed and mixed with new materials in a certain proportion for use. Generally, new film production lines are equipped with this device. This method also helps reduce costs. www.handern.com Non-woven equipment
(3) Composite film technology plastic recycled materials often have low freedom of appearance and color. The general color is gray to black, and other colors are restricted. Limited for this purpose. We have to make only products with low added value. In order to break this limitation, we can consider using composite layer molding. The middle layer is recycled material. The inner and outer layers are new materials, and their quality and appearance are not inferior. For example, a three-layer film with recycled materials in the middle. This method is also used in many factories. www.handern.com Non-woven equipment
