Production of PLA biodegradable film blowing machine equipment, which produces biodegradable films suitable for covering vegetables, fruits, tobacco, and crops.
1. Ordinary plastic film can easily lead to reduced yield
The main component of non degradable plastic film is polyethylene, which remains in the soil and is extremely difficult to decompose. A large amount of residue hinders the transportation of water and nutrients in the soil, and the plastic film in the soil damages the soil structure, leading to deterioration of the soil environment, affecting crop growth and development, and resulting in reduced yields.
2. Serious pollution of ordinary plastic film
At present, agricultural plastic film pollution in China is very severe. For several consecutive years, during the National People's Congress and the Chinese People's Political Consultative Conference, many representatives and members have proposed proposals related to strengthening the research and development of plastic film pollution technology. This not only has an impact on contemporary people, but also on future generations.
Advantages of biodegradable plastic film
What are the advantages of biodegradable plastic film?
1. Moisturizing, insulating, and fertilizing
The new type of plastic film not only can automatically degrade, but also has outstanding moisturizing and insulation effects. Anrui testing showed that after covering with plastic film, keeping the soil moist can increase the soil temperature by 2 ℃ -4 ℃, which is beneficial for the growth of crop roots and early fruiting. Plastic film can also prevent rainwater erosion, effectively improve soil fertility, and create a good growth environment for crops. Once promoted in the future, it will be a very valuable product.
2. Automatically degradable
Degradable plastic film is different from ordinary plastic film in that it does not cause harm to the soil and can be automatically degraded after use. Degradable plastic film is made from polymer materials such as PBAD, polylactic acid, or starch. Through oxidation, microorganisms digest, absorb, and utilize it, transforming it into carbon dioxide, water, and humus, which are integrated into the soil.
The biggest difference between biodegradable plastic film and ordinary plastic film is that biodegradable plastic film has biodegradability, while ordinary plastic film does not. Degradable plastic film is made of biomacromolecule materials such as starch, polylactic acid, etc. After treatment, it can be decomposed and degraded by microorganisms in soil, ultimately forming non-toxic and harmless water, carbon dioxide, and biomass. Ordinary plastic film is made of non degradable materials such as polyethylene, which cannot be degraded by the natural environment. It exists in the soil for a long time and is harmful to the soil, affecting soil fertility and the survival of microorganisms. At the same time, it also brings pollution and impact to the environment.
The advantage of this device lies in:
1. Solve the problems of overheating of extruder screws and decomposition of mold flow channels for biodegradable raw materials,
2. The screw adopts water cooling to solve the problems of processing temperature overheating and raw material decomposition
3. The mold adopts a new channel design to improve the drawbacks of poor flowability of raw materials and poor compatibility of molecular structure
4. A specialized new type of rewinding machine solves the problem of wrinkling and stretching deformation of thin plastic film.
5. A dedicated air ring solves the drawbacks of degradation film, slow cooling, and low yield
6. Adopting AB co extrusion. Solving the difficulty of single formula and special process for degradable materials. Adapt to the processing of mixed materials.
