Stretch Film Wholesale
Stretch film consists of thin, transparent plastic sheets primarily made from low-density polyethylene (LLDP). This film is used for packaging industrial products and protecting them during warehousing and transportation. Due to the physical strength present between the molecular chains, this product has high tensile strength and durability, and it also possesses strong adhesive properties for holding product bundles together.
Production Compositions
As mentioned, stretch film is generally made from LLDPE resin; this copolymer is a combination of ethylene and alpha-olefins (C₄–C₁₀), providing a balance of flexibility and high tensile strength to the film. To enhance performance, additives such as slip agents, anti-blocking agents, and in manual-grade samples, tackifiers for increased adhesion are added to the formulation. In machine-grade samples, resistant fillers are used to increase puncture resistance.
Types of Stretch Films
Agriculture Stretch
In agriculture, 7-layer co-extruded PE stretch films, such as AgroWrap and TECBALE, are employed to safeguard silage bales. These films offer enhanced resistance compared to 5-layer variants, ensuring airtight seals and optimal fermentation conditions. Colored options, like white or green, minimize heat absorption, preventing overheating of the silage. Notably, these stretches provide UV resistance for up to 12 months, preserving feed quality throughout storage.
Industrial Stretch
In industrial settings, PE stretch films are integral for securing palletized products. They prevent moisture ingress, shield against dust and dirt, and offer protection from physical impacts. The global stretch wrap market, valued at USD 4.68 billion in 2025, is projected to reach USD 6.71 billion by 2032, reflecting a CAGR of 5.27%. This growth underscores the increasing reliance on stretch films for efficient and safe product transportation.
Food Stretch
PE stretch films play a crucial role in the food industry by maintaining hygiene and extending shelf life. They are widely used for wrapping fresh produce, meats, and ready-to-eat meals. The global stretch film market for food packaging is experiencing robust growth, driven by the rising demand for convenient and safe food packaging solutions. Advancements in film technology, including the development of sustainable and biodegradable alternatives, are further propelling this market.
Features of Stretch Film
High tensile strength: Some models of machine-grade products can withstand tensile strengths of up to 25 megapascals.
Adhesion and transparency: Stretch films have adequate adhesive power to securely hold product bundles together during packaging and prevent them from being damaged or disturbed. Additionally, this film has a transparent surface that allows for visibility of the packaged contents.
Resistance to tearing and puncturing: Reinforced types can withstand puncture forces of 4–6 pounds (17.8–26.7 newtons).
Biodegradable: If needed by the customer, environmentally friendly stretch films are produced and supplied to reduce the carbon footprint.
Variety in thickness and width: Thickness ranges from 12 microns (15 gauge) to 55 microns (45 gauge), and width can be selected from 200 to 1500 millimeters.

Applications in Industries
Logistics and Palletizing
In the logistics sector, PE films, particularly stretch films, are essential for stabilizing and protecting palletized loads. Their high elasticity allows for tight wrapping, preventing shifting during transportation and optimizing warehouse space. Notably, stretch films constitute approximately 18% of PE applications in Europe, underscoring their pivotal role in non-food packaging.
Food and Beverage Distribution
PE films play a crucial role in bundling items like bottles and cans in the food and beverage industry. They maintain hygiene by providing a protective barrier against contaminants and reduce the risk of product tampering. Additionally, their clarity allows for product visibility, which is beneficial for retail presentation.
The food packaging films market was valued at USD 49.8 billion in 2021 and is projected to reach USD 72.3 billion by 2027, growing at a CAGR of 6.4% from 2022 to 2027.
Manufacturing and Warehousing
In manufacturing and warehousing, PE films are used to shield final products and raw materials from dust and moisture. This protection is vital for maintaining product integrity during storage and handling.
Approximately 41% of PE flexible films are utilized for non-food packaging applications, including stretch and shrink, highlighting their importance in industrial settings.
Export Packaging Protection
For international transport, PE films provide a resilient layer that withstands environmental conditions and temperature fluctuations. This ensures that products reach their destination in optimal condition, complying with global shipping standards and reducing the likelihood of returns or replacements.
