Degradable protective film substrates are available

With increasing attention to environmental protection, degradable protective film substrates are gradually developed and applied. These substrates can be broken down into smaller compounds under certain conditions, reducing the impact on the environment.

The following are some of the current degradable protective film substrates:

  1. PLA (polylactic acid): PLA is a biodegradable plastic, usually based on plant raw materials such as corn starch. It can be decomposed into water and carbon dioxide under certain environmental conditions and has little impact on the environment. PLA protective film is often used in food packaging, agricultural covering film, and other fields.
  2. PBAT (polybutanediol succinate): PBAT is a synthetic biodegradable plastic, usually mixed with other bioplastics such as starch. It can be gradually broken down into small molecules in the natural environment, reducing plastic pollution. PBAT protective film is widely used in disposable items, packaging film, and other fields.
  3. PHA (polyhydroxy fatty acid ester): PHA is a class of biosynthetic plastics that can be produced from microbial fermentation. It has good biodegradability and can decompose in soil and water bodies. PHA protective films are used in some agricultural and packaging applications.
  4. Starch-based materials: Starch is a natural polysaccharide that can be used to make degradable plastics. Starch-based materials can be made into degradable protective films by doping, blending, and other methods, and they will decompose into smaller compounds in the appropriate environment.
  5. Polycaprolactone (PCL): PCL is a synthetic plastic that has a relatively low degradation rate, but can also decompose under the right conditions. PCL protective films are used in the medical field and in some temporary applications.

degradable protective film

These degradable protective film substrates can be gradually decomposed under the right conditions, reducing the ongoing impact on the environment. However, it is important to note that being biodegradable does not mean that these membranes can be arbitrarily discarded anywhere. They may need to be processed in specific treatment facilities to ensure proper degradation and resource utilization.

Reasons for the layer of protective film

The reasons for the lamination of protective film can be many, usually involving material quality, manufacturing process, environmental factors, etc.

Here are some common causes that can cause layer of protective film:

  1. Poor material quality: If the quality of the material used is unstable or does not meet the requirements, there may be non-uniformity within the material, or the adhesion of the material is not good enough, which may lead to the lamination of the protective film in use.
  2. Manufacturing process problems: The process of manufacturing the protective film may affect the layering problem. If the temperature, pressure, coating speed, and other parameters in the manufacturing process are not properly controlled, it may lead to uneven bonding of the material, resulting in delamination.
  3. Poor adhesion: The protective film needs to be firmly attached to the substrate or the surface of the protected object. If the attachment is not good, stratification may occur during use.
  4. Temperature and humidity changes: Changes in temperature and humidity may cause the material of the protective film to expand or contract, thus affecting the bonding performance. Especially under extreme temperature and humidity conditions, the delamination problem may be more prominent.
  5. Chemical reaction: The chemical properties of the protective film and the surface of the protected object may interact, resulting in a chemical reaction of the material, resulting in delamination. For example, chemical incompatibility can lead to material separation between the protective film and the object being protected.
  6. External damage: The protective film may suffer physical damage during use, such as scratching, impact, etc., which may lead to the rupture or delamination of the film material.
  7. Storage and transportation conditions: the protective film is affected by environmental conditions such as temperature and humidity during storage and transportation, which may affect the stability and adhesion performance of the film, resulting in layering problems.

layer of protective film

To avoid the lamination problem of protective film, manufacturers usually need to ensure that the material quality is stable, the manufacturing process is reasonable, the adhesion is good, and extreme environmental conditions are avoided during use. In addition, the correct use and maintenance methods can also reduce the risk of protective film delamination.

A diaphragm is a protective film that sits between the positive and negative electrodes and prevents the flow of direct electrons and ions but allows ion exchange. This helps prevent short circuits and overheating of the battery and improves the safety of the battery.
  2. Battery shell protective film: The battery shell needs to be protected to prevent external substances such as moisture, dust, and pollutants from entering the battery interior and affecting its performance. The case protective film can be attached to the surface of the battery case to provide an additional layer of protection.
  3. Pole film protection film: the positive and negative electrodes of the battery are usually connected through the pole film, which needs to be protected from the external environment. A protective film can be applied to the electrode sheet to prevent accidental contact between it and the electrolyte.
  4. Battery label protective film: Lithium batteries are usually attached with battery information, model, and warning labels. These labels need to be protected to prevent the labels from being damaged or falling off, thereby preventing users from correctly identifying the battery’s performance and precautions.
  5. Battery component protective film: During the battery assembly process, various components need to be protected to prevent damage during assembly and transportation. Protective films can be used to protect cell cells, modules, and components of the entire battery pack.

 

In general, the protective film plays an important role in the protection and safety performance of the lithium battery industry, preventing damage to the internal components of the battery and the impact of the external environment, thereby improving the life, stability, and safety of the lithium battery.
