There are various types of Taiwan stretch film that businesses can choose from. Each type comes with unique characteristics and advantages. These attributes make them suitable for different wrapping and packaging needs.
Cast Stretch Film
Cast stretch film is produced using a flat-die casting process. This method of production leads to a film that is clear, has a consistent thickness, and is easy to apply. It is known for being stretchy and resilient, which helps it stick to itself securely without a tight wrap. Since it is very transparent, cast film is great for showing off or checking on items. It works well with automatic wrapping machines, so it is often used to boost productivity in large operations.
Blown Stretch Film
Blown stretch film is made by blowing the film into air bubbles. This gives the film more strength and is useful for wrapping irregular loads. The manufacturing process creates thicker edges and a more uneven surface than cast film. While this may reduce crystal clear visibility, it actually helps the film grip better. This film resists punctures and tears, providing reliable protection during shipping and storage. Companies often choose blown film for tougher jobs requiring extra durability.
Vented Stretch Film
Vented stretch film incorporates tiny holes throughout the sheet. These vents allow air to escape while still sealing the load tightly. This film is useful for wrapping wet products like produce, meat, or seafood. The holes let moisture and air out so the wrapped film does not get wet and lead to molds or spoiling. It fits around loads firmly and keeps items together securely during transport. Many teams choose vented film as an affordable way to keep food fresh and deliver it safely.
Pre-Stretched Film
Pre-stretched film is stretched beforehand. This process gives the film already perfect tension before application. The equal stretch across the sheet stops uneven pulls that cause rips. Since the film is set at its stretch level, users apply it with lighter force. This film uses less wrapping per load while still fully protecting items. Its consistent pull helps film course through machines properly. Warehouses use this film to pack loads faster, simpler, and with better strength in each bundle.
The versatility of stretch film in Taiwan packaging solutions extends beyond general usage. This is especially true because of its growing applications in several important industrial sectors.
Wrapping Pallets for Shipment
Stretch film is commonly used to wrap and securely package inventory on pallets before shipment. Its ability to cling tightly to itself and form a secure package makes it ideal for stabilizing loads during transport. In logistics and warehousing, machine-applied stretch film quickly wraps large volumes of pallets, enhancing efficiency. The film protects products from shifting, weather, and general handling. This application helps maintain the integrity and safety of goods delivered via trucks or freight.
Sealing Containers for Security
Whether it is cardboard boxes or plastic bins, stretch film effectively seals containers to safeguard contents from tampering or theft. Stretchable film applied tightly across container openings ensures nothing can be accessed without visible evidence of unauthorized entry. Security seals may be impractical for very large assemblies or continuous production items. Vented stretch film provides breathable packaging for perishables while still securing against pests. These characteristics make stretch film useful for wrapping products requiring security during extended warehousing, distribution, or international shipping.
Bundling Items like Tools or Equipment
Many industrial-tool packages feature items such as hoses, cables, or handtools bundled neatly together using stretch film. Its ability to tightly wrap uneven shapes helps contain dissimilar items without leaving residue on the surfaces. Blown or cast stretch films accommodate awkwardly shaped loads better than tighter films, increasing bundle pick-up rates during sorting and distribution. Pre-stretching the film also creates firmer bundles that withstand prolonged handling through construction sites, manufacturing plants, or distribution centers.
Adding a Layer of Protection to Goods
The inherent puncture resistance of blown stretch film acts as an additional safeguard during storage, particularly for exposed power tools, fragile components, or sharp materials prone to damage. This application is commonly employed when items need extended safeguarding from dust accumulation, environmental exposure, or moisture. The outer layer of stretch film prevents items from becoming dented, scratched, or otherwise marred while stored in warehouses, on loading docks, or inside delivery vehicles. Compared to other formats like bubble wrap, stretch film requires less retrieval time when needed.
Stretch film is typically constructed from linear low-density polyethylene (LLDPE). This plastic formulation combines stretchability with robust tensile strength. Common gauges range from 50 to 120 microns (2 to 4 mils), depending on application requirements. Key features include:
Tight Cling Without Heat
Stretch film adheres tightly to itself, forming a secure package that holds items tightly together without the need for adhesives or heat bonding. This self-adhesive quality ensures stable protection during transit and storage.
Exceptional Stretch and Puncture Resistance
Constructed from tough polyethylene, stretch film boasts remarkable elasticity, allowing it to accommodate various load shapes. It maintains its integrity and safeguards against sharp edges or rough surfaces through superior puncture resistance and durability.
Load Stabilization
The film, when meticulously applied, enhances load stability by mitigating individual item movement within a package. This stabilization reduces the likelihood of product damage during transportation.
UV Protection
Certain variants of stretch film integrate ultraviolet (UV) shielding. This feature is especially advantageous for safeguarding products sensitive to sunlight exposure, such as furniture, electronics, or agricultural goods. It effectively hampers the potential for discoloration or material degradation.
Temperature and Environment Tolerance
Packing items in stretch film creates an insulating layer around the package. This helps the items to withstand various temperatures and environmental conditions. This keeps the items at room temperature and protects them from dust, rain, and other elements.
Recyclable Plastic
Stretch films, including hand-grade stretch film, can be recycled alongside other plastic products. Some manufacturers offer take-back programs for commercial users to encourage recycling and reduce environmental effect.
Stretch film suppliers on Alibaba.com should consider these factors when choosing stretch films for customers in Taiwan. These factors also impact the customers' overall satisfaction with the product.
Purpose
Buyers should first determine the stretch film's intended use. Will customers use it for machine pallet wrapping or manual wrapping? Will they use it for load stabilization or for unitizing products? Understanding the Taiwan stretch film's primary purpose will help decide how strong, durable, and adhesive the film should be.
Width and Gauge
The width and thickness (or gauge) of the film greatly affect its protective properties. A thicker film is better for wrapping heavy or irregular loads, while a thin film can suffice for lighter items. In Taiwan, standard stretch film is available in widths of 250 mm to 1,500 mm and gauges of 50 to 300 microns. Buyers should also note that a thicker film is harder to puncture or tear, which provides mechanical strength, and a thinner one is easier to apply by hand.
Type
Cast stretch film is ideal for customers requiring clear visibility and consistency, such as retail packaging. On the other hand, blown stretch film bundles offer superior cling and puncture resistance. This makes it suitable for heavy items or rough surfaces. Pre-stretched film provides even tension, making it a good choice for machine applications that require a smooth finish.
Adhesion
Some stretch films are designed with higher adhesion levels to ensure the layers stick to themselves without slipping. This is particularly important for stacking goods during storage and shipment. Customers also have the option of choosing film grades with specially formulated adhesive properties. They can help them achieve a certain application, like temperature extremes or wet surfaces.
Recycling
Buyers prioritizing eco-friendly practices can stock up on recyclable stretch films. Many of these options are manufactured from post-consumer recycled materials or designed to be easily recyclable afterward. Hence, these options will be useful for retailers who want to promote sustainability.
A1: For typical purposes, stretch film with a thickness of 80 to 120 microns works properly. This gauge offers enough stretch, puncture resistance, and load security for packing lightweight to medium-weight items, including those frequently found in retail or warehouse environments.
A2: It is worth it if the customers want to secure the packages or use the films for advertising. Branded and tinted films improve confidentiality by hiding the contents. They may also increase brand exposure by establishing a unified aesthetic for marketing functions.
A3: Stretch film with ventilation holes is ideal for wrapping perishable foods like fruits, vegetables, and meats. The small vents allow air to pass through while keeping insects out. This keeps the food fresh during transport and storage.
A4: Stretch film is specifically designed to cling to itself without the need for heat. This makes it great for stacking items on pallets and securing them during transport. However, shrink film requires heat to conform tightly around individual items or pallets. This offers a snug, custom fit that provides a different level of protection.
A5: Yes, many types of stretch film, such as those made from polyethylene, can be recycled. This recycling often occurs alongside other plastic films. However, it's important that customers check local recycling guidelines to confirm proper recycling methods in their area.
