Wuhan Handern Packaging Materials
The repeated regeneration and recycling of packaging materials is the most practical step in the development of green packaging materials, and it is one of the most active waste recycling methods for protecting the environment and promoting the recycling of packaging materials. In foreign countries, PET beverage bottles and PC feeding bottles can be reused more than 20 times. Examples of reusable films are the sealing films discussed in section 2.1.3.7, which can be used repeatedly. The film medicine bag of the outpatient sealing product of the hospital can be repeated many times www.handern.com hollow board equipment.The recycling of general plastic packaging waste includes the combustion method, landfill method, and recycling. More requirements are recycling, and landfill should be reduced to zero. www.handern.com Hollow board equipment.
Self-recycling of plastic film waste is more difficult than ordinary rigid plastics, and the current commonly used methods are as follows:
(1) The thick film is attached with a recycling mark to facilitate recycling and reuse, such as general PE heavy packaging films and thicker films. When printing packaging bags, the recycling mark is printed at the same time, which is convenient for recycling. In order to facilitate the recycling of plastic waste, various advanced countries have formulated identification marks and plastic recycling volumes and general light packaging films. It may be difficult to implement recycling marks, but as long as you persist and take effective measures, you should compare Landfill is better. To some extent, it is more advantageous than using degradable plastics www.handern.com hollow board equipment.
(2) Recycling of product waste from the corner waste in the factory by its own, the source of occurrence is clear, and the classification and quantity of materials are easy to grasp. Therefore, it is the most effective method to recycle and apply thoroughly in the factory, and use the waste of each process to use the entire waste to form a closed system for regeneration. For example, the edge-cutting waste during film production is crushed and mixed with new materials at a certain ratio. Generally, new-type film production lines are equipped with this device. This method is also conducive to reducing costs. www.handern.com Hollow board equipment. www.handern.com Hollow board equipment.
(3) Composite thin film technology plastic recycled materials often have low appearance and color freedom. The general colors are gray to black, and other colors are restricted. Restricted for this purpose. You have to make only products with low added value. In order to break this limitation, 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 3-layer film with a recycled material in the middle, this method is also used in many factories. www.handern.com Hollow board equipment.
