PVC film (Polyvinyl Chloride Film) is a plastic film made primarily from polyvinyl chloride resin. It exhibits excellent flexibility, weather resistance, flame retardancy, and processability, making it widely used in packaging, decoration, industry, and advertising. Due to its cost advantages and diverse surface treatment options, PVC film also holds a significant position in the artificial Christmas tree industry, serving as one of the primary materials for making Christmas tree leaves.
PVC film is a plastic film made by mixing polyvinyl chloride resin with additives such as plasticizers, stabilizers, lubricants, and colorants. Based on the degree of flexibility, it can be categorized as follows:
PVC Soft film: Soft and bendable, suitable for packaging, decoration, and other fields.
PVC Rigid Film: Highly hard and stiff, it is commonly used for protective and structural applications.
Strong Plasticity
PVC film has many applications. According to its different characteristics, it can be made into Christmas tree film, food packaging film, label film, etc.
Weather Resistance
PVC film is resistant to acids, alkalis, salts and some chemicals, and can remain normal in most environments and has a certain degree of weather resistance.
Good Printability
PVC film is easy to color. For example, PVC Christmas film can be customized according to the needs. It can also be made into a glossy matte effect.
Flame Retardance
PVC film has good flame retardancy and can achieve a higher flame retardancy level after adding flame retardants.
Extrusion
The mixed raw materials enter the extruder, where the screw rotates within a heated barrel, heating, shearing, and melting the raw materials into a uniform, plasticized melt.
Temperature Control: Heating is typically performed in multiple stages to ensure the resin is fully plasticized without decomposing.
Filtration: The melt passes through a filter to remove impurities and ensure a smooth film surface.
Die Forming: The melt is uniformly extruded through a flat die (T-die) to form a continuous sheet.
Calendering
In calendering, the molten material passes through multiple sets of heated rollers to form a film of the desired thickness. This calendering process produces a smooth, uniformly thick finished product and allows for direct embossing of textures.
Packaging Industry: Food packaging film, shrink film, label film.
Decoration Industry: Christmas tree leaves, ribbons, window stickers, wall stickers.
Industrial Uses: Waterproof film, anti-corrosion film, cable sheathing.
Advertising and Signage: Inkjet printing film, light box film, vehicle body film.
In Christmas tree manufacturing, PVC film is often cut into filaments or needles to form the leaves. It can be easily dyed to create artificial Christmas trees in a variety of colors, meeting the decorative needs of various markets. PVC film can also be formulated with flame-retardant formulations to enhance safety while maintaining low costs and high production efficiency.
PVC film can be recycled and reused in products such as flooring and pipes. In recent years, environmentally friendly PVC film has been gradually promoted, using lead-free stabilizers or biodegradable formulas to reduce the impact on the environment.
