Shrink Bags

Shrink bags are heavy-duty plastic bags that use heat to tightly conform around palletized loads, while stretch wrap relies on film tension to secure products.

Millwood shrink bags create a strong, tamper-evident seal by shrinking uniformly when exposed to heat. This provides five-sided coverage that protects against dust, dirt, bacteria and contamination. Unlike stretch film, which can leave gaps, shrink bags offer a complete barrier for sensitive or heavy-duty applications. They are ideal for products stored outdoors or in demanding industrial environments, where extra protection and security are critical. By providing superior sealing and moisture resistance, shrink bags deliver long-term reliability and stronger pallet protection than standard stretch wrap.

Shrink bags offer tamper-evidence, weather resistance and improved cargo stability, making them essential for heavy-duty palletized shipments.

Millwood’s shrink bags are engineered to safeguard products against environmental factors like dirt, bacteria and moisture. Their tight, uniform seal prevents load shifting, ensuring pallets remain stable throughout transit and storage. Custom sizing allows for better fit, reducing material waste and improving efficiency. Shrink bags are especially effective for export shipments, outdoor storage and high-value products requiring maximum protection. By lowering product damage, shrink bags reduce claims and replacement costs, making them a cost-effective, high-performance packaging solution across multiple industries.

Heat shrink bags work by being placed over a pallet load and then heated, causing the film to shrink tightly around the cargo, creating a secure, tamper-evident package.

Millwood shrink bags are designed for industrial-strength performance. The heat application process pulls the material snug against the load, improving unitization and ensuring stability during transport. This process also enhances protection against moisture and contamination while deterring tampering. When used with Millwood Shrink Wrap System equipment, the application is consistent and efficient, providing reliable results every time. The end result is a palletized shipment that is stronger, safer and better protected against damage and environmental exposure.

Yes—shrink bags can be custom-manufactured in a wide range of sizes to fit specific pallets, unique load shapes and industrial requirements.

Millwood designs shrink bags to customer specifications, ensuring a proper fit for maximum performance. Custom-fit shrink bags eliminate excess material, reduce waste and improve the efficiency of packaging operations. Whether a load requires oversized coverage or tailored protection for irregular shapes, Millwood can engineer shrink bags that deliver dependable containment and sealing. By offering customizable options, Millwood helps businesses optimize their packaging process, improve load security and achieve greater cost efficiency while maintaining product integrity.

Shrink bags require heat-application equipment, such as Millwood’s Shrink Wrap System, to shrink and seal bags securely around pallets.

The Shrink Wrap System ensures consistent heating for a uniform seal, reducing labor time and improving packaging reliability. This equipment is designed for heavy-duty shipping and industrial use, making it an essential part of the shrink bag application process. Using the right equipment ensures shrink bags perform at their highest level, providing strong seals that withstand handling, stacking and outdoor conditions. Millwood’s combination of custom shrink bags and specialized application systems offers businesses a comprehensive, reliable solution for secure cargo protection.
