Popular Science on the Composition of PVC Plastic Soft Film

    The main component of PVC plastic soft film is polyvinyl chloride (PVC) resin. This is a high molecular weight polymer polymerized from vinyl chloride monomer, which is the basic material of PVC soft film and provides the fundamental structure and performance foundation for the soft film. In addition to PVC resin, it also contains plasticizers. The commonly used plasticizers are phthalates, such as dioctyl terephthalate (DOTP). Plasticizer molecules are inserted between the molecular chains of PVC resin, increasing the intermolecular distance and reducing the intermolecular forces, thereby making the PVC soft film soft, elastic, easy to bend and stretch.
     Stabilizers are also important components, such as barium cadmium stabilizers, calcium zinc stabilizers, etc. Due to the susceptibility of PVC to degradation reactions caused by factors such as heat and light during processing and use, stabilizers can effectively prevent PVC decomposition, improve the thermal and photostability of PVC soft films, and ensure the stability of their physical and chemical properties. In addition, there are lubricants such as stearic acid, paraffin, etc. Lubricants can reduce the friction between PVC and equipment during processing, making the process smoother and improving the surface glossiness of PVC soft film.

    In addition, it may contain a small amount of antioxidants, such as hindered phenolic antioxidants, which can prevent PVC soft films from oxidizing, discoloring, and aging in the air, thereby extending their service life; There may also be some coloring agents used to meet different color requirements, making PVC soft film more diverse in appearance.Qualified PVC film is non-toxic under normal use.The chemical properties of PVC film itself are relatively stable. In the process of producing qualified PVC film, the types and amounts of additives (such as plasticizers, stabilizers, etc.) will be strictly controlled. Non toxic plasticizers that meet national standards will be used to achieve softness and other properties in PVC films, and these plasticizers will not pose any harm to the human body.
    Moreover, when PVC film is used for food packaging and other purposes, it needs to undergo strict food safety testing to ensure that no toxic substances migrate into the food. For example, PVC cling film used for packaging vegetables, as long as it is a legitimate product, will not release toxic ingredients during contact with food.

So PVC plastic film has many uses.

    In the field of architectural decoration, PVC plastic soft film can be used for indoor ceiling decoration. It can create different spatial atmospheres through various styling designs, such as simulating starry skies, blue skies, white clouds, and other effects. Moreover, it has excellent waterproof properties and can be used in damp places such as kitchens and bathrooms to prevent damage to the ceiling due to moisture.In the advertising industry, PVC plastic soft film is an important material for making lightbox advertisements. Its excellent transparency enables lightbox advertisements to emit light uniformly, with bright colors and good display effects. At the same time, the flexibility of the soft film allows it to be processed into various complex shapes to meet different design requirements.
In the furniture industry, PVC plastic soft film can be used for covering the surface of furniture. For example, veneering furniture such as tables, chairs, and cabinets can protect the surface of the furniture, prevent scratches and wear, and provide a variety of texture and color options to increase the aesthetics of the furniture.In the packaging industry, PVC plastic film can be used as a flexible packaging material. For small electronic products, toys, stationery, and other goods, PVC soft film packaging can provide good dust and moisture resistance, and can clearly display the appearance of the product.In the medical industry, PVC plastic flexible film that meets medical grade standards can be used to make outer packaging for medical devices, medical gloves, infusion bags, etc. Its flexibility and non-toxic properties (in compliance with standards) can well meet the requirements of medical use.
