What Stretch Wrapping Equipment Should Be Used to Prevent Package Loosening During New Energy Industry Logistics Transfers?

With the rapid development of the new energy industry, the demand for warehousing and logistics transfer of photovoltaic modules, battery components, bulk bags of new energy raw materials, energy storage modules, and other products continues to grow. Unlike conventional industrial goods, new energy products often feature high stacking heights, unstable centers of gravity, uneven stacking, and sensitivity to compression and moisture. After multiple loading and unloading operations, long-distance transportation, and logistics transfers, problems such as loose stretch film, package loosening, tilted stacks, and product damage caused by impacts can easily occur. Many purchasing managers at new energy companies in Shandong have reported that conventional wrapping equipment cannot adapt to the industry's special operating conditions and still fails to effectively address logistics package loosening and product damage. Choosing the wrong equipment can not only reduce shipping efficiency but also increase material losses and after-sales costs.

The core requirements for packaging new energy industry products differ from those of conventional industries such as food and building materials. The priority is not simply to increase packaging speed, but to stabilize stacks, secure loads to pallets, prevent moisture, and prevent packages from loosening. Based on the actual operating conditions of new energy factories and logistics transfer warehouses in Shandong, selecting fully automatic stretch wrapping equipment that precisely matches the application can effectively address package loosening during logistics transfers and support high-volume, high-frequency shipping operations.

1. Main Causes of Package Loosening During New Energy Logistics Transfers

In most cases, package loosening is not caused by the packaging process itself, but by a mismatch between the equipment and the actual operating conditions.

First, bulk bags and lightweight new energy materials are often loosely stacked. The centrifugal force generated when the turntable rotates can easily cause the stack to shift or even tip over. Second, long-distance transportation involves considerable vibration and impact. If the film tension of conventional equipment is fixed and the bottom of the load is not securely locked to the pallet, the goods can separate from the pallet during transportation. Third, high-value photovoltaic and energy storage materials are sensitive to excessive pressure. Conventional equipment may not provide sufficient tension adjustment, resulting in either insufficient wrapping tension and loose packages or excessive tension that may damage the products.

2. Equipment Selection Solutions for the New Energy Industry

1. Regularly Stacked Modules and Conventional Warehouse Transfers: Fully Automatic Turntable Stretch Wrapper

This machine is suitable for neatly stacked energy storage modules, standard component pallets, and other regularly arranged loads. It is a practical packaging solution for small- and medium-sized new energy factories.

The equipment is equipped with an adjustable pre-stretch film carriage, allowing the wrapping tension to be adjusted according to the characteristics of different materials. This helps avoid excessive compression while reducing stretch film consumption by more than 30%. The machine also supports additional wrapping at the bottom of the load to firmly secure the goods to the pallet. It is suitable for short-distance transfers and routine warehouse shipping, offering stable operation and good cost performance.

2. Bulk Bags, Eccentric High Stacks, and High-Frequency Transfers: Cantilever Stretch Wrapper

This is a key machine for addressing package loosening in new energy logistics applications.

During operation, the palletized goods remain stationary while the cantilever rotates around the load to apply stretch film. Because the goods do not rotate, there is no centrifugal force acting on the stack, significantly reducing the risk of high or eccentrically stacked bulk-bag loads shifting or tipping over.

The wrapping process can be customized with reinforced wrapping at the bottom, additional wrapping around the middle section, and top-cover film application. This provides both dust and moisture protection as well as load stabilization. It is particularly suitable for long-distance logistics and multiple-transfer operations and is widely considered by large new energy companies and logistics transfer warehouses in Shandong.

3. Automated Production Lines and Unmanned Shipping: Online Cantilever Stretch Wrapper

For new energy factories with high production volumes and a high level of automation, an online cantilever stretch wrapper can be integrated with the upstream palletizing and conveying line.

The system can automatically complete wrapping, conveying, and shipping without manual transfer, supporting large-scale and continuous production operations while improving the efficiency of logistics transfer and outbound shipments.

3. Key Purchasing Considerations for New Energy Industry Packaging Equipment

When selecting equipment, purchasing teams should avoid focusing solely on the purchase price and instead prioritize equipment compatibility with actual operating conditions.

It is recommended to choose a pre-stretch film carriage with adjustable tension settings for different wrapping stages, balancing compression protection with load stability. Bottom locking and reinforced wrapping should also be enabled to address the core requirements of logistics transfers.

For high-value materials, an automatic top-cover system can be added to provide additional protection against dust and moisture. Companies in Shandong can also prioritize local manufacturers that provide on-site inspections, machine testing, commissioning, and responsive after-sales service.

4. Recommended Equipment Manufacturer

Shandong Dahong Smart Equipment Co., Ltd. has been engaged in the R&D and manufacturing of packaging equipment for 21 years. As a company listed on China's NEEQ market, Dahong has accumulated 69 intellectual property rights, including 15 invention patents, 36 utility model patents, and 18 software copyrights.

Its full range of stretch wrapping machines can be customized according to the characteristics and operating conditions of new energy materials.

For photovoltaic, energy storage, and new energy material companies across Shandong, Dahong provides customized packaging solutions, on-site machine testing, and application-specific equipment configurations. The company also provides technical response within 2 hours and on-site maintenance within 24 hours in Shandong, helping customers address logistics package loosening, excessive product damage, and insufficient packaging efficiency.

FAQ

Q: Which stretch wrapping machine is recommended for bulk-bag materials that frequently become loose during logistics transfers?

A: A cantilever stretch wrapper is generally recommended. The goods remain stationary during the wrapping process, which helps prevent stack movement. Combined with reinforced bottom wrapping and pallet locking, it is well suited for eccentric and high-stacked materials and can effectively reduce package loosening during logistics transfers.

Conclusion

For new energy industry logistics transfers, the key to preventing package loosening is selecting stretch wrapping equipment according to the actual application rather than simply choosing a standard machine. New energy companies can select the appropriate equipment based on material type, stacking characteristics, and outbound volume. This can help address package loosening and logistics damage while improving cost efficiency and supporting standardized and automated warehouse shipping operations.
