Polyolefin shrink film is a premium, multi-purpose shrink packaging material derived from a blend of polyolefin polymers, primarily polyethylene (PE) and polypropylene (PP). Engineered for high-performance packaging applications, this film is biaxially oriented—stretched in both the machine and transverse directions—to provide exceptional clarity, strength, and uniform shrinkage.
When exposed to controlled heat, polyolefin shrink film contracts evenly around the product, creating a tight, smooth, and tamper-evident seal. Its optical transparency enhances product presentation, while its flexibility and toughness make it ideal for protecting items from dust, moisture, and handling damage.
Widely used in sectors such as food and beverage, cosmetics, electronics, pharmaceuticals, printing, and retail, polyolefin shrink film offers numerous advantages over traditional materials like PVC. These benefits include:
Non-toxic sealing with low odor emissions
High durability and puncture resistance
Superior cold-temperature performance
Compatibility with high-speed packaging lines
Environmental friendliness—often recyclable and compliant with food safety standards
Polyolefin shrink film is available in various formulations, such as cross-linked for enhanced strength or anti-fog for refrigerated products, allowing manufacturers to select the ideal type for their specific application.

Production and development of various special shrink films and wrapping films to meet the different needs of customers
Polyolefin Shrink Films are now sought Shrink Films in the Packaging Industry. These shrink films offer 80% shrinking properties (both directions) along with better transparency and remains odourless when heated and cooled. POF Shrink Films does not emit Chloride on heating, this is an important advantage over PVC Shrink Films.
Polyolefin Shrink Film (POF Shrink Film) is a versatile, heat-shrinkable material primarily made from a blend of polyethylene (PE) and polypropylene (PP). The film is created through a process called extrusion, where these polymers are melted and formed into thin, transparent films. The key component of POF is the combination of copolymerization between polyethylene and polypropylene, which gives the film its strength, clarity, and elasticity.
Polyethylene (PE) provides the film with a smooth surface and exceptional strength.
Polypropylene (PP) contributes to the film's high shrinkage rate, flexibility, and resilience.
Polyolefin Shrink Film has gained widespread popularity due to its combination of versatility, performance, and eco-friendly attributes.

Polyethylene (PE): The most commonly used material in shrink films due to its cost-effectiveness and durability.
Low-Density Polyethylene (LDPE): Provides a soft and flexible shrink film, used for packaging applications that do not require extreme strength.
High-Density Polyethylene (HDPE): Offers stronger, more rigid shrink films for heavy-duty applications.
Polypropylene (PP): Often used in Polyolefin Shrink Films because of its high shrinkage rate, clarity, and strength. It provides better heat resistance than polyethylene and offers a smoother finish.
Polyvinyl Chloride (PVC): PVC is used in some shrink films but has largely been replaced by Polyolefin films in many applications due to the environmental concerns associated with chlorine emissions from PVC.
Other Additives:
Plasticizers: Used to enhance flexibility in some shrink films.
UV Stabilizers: Protect the film from degradation due to exposure to sunlight.
Anti-Static Agents: Prevent static accumulation during the packaging process.
Colorants: To provide a colored or opaque finish if needed for branding or aesthetics.
