Is the top prone to dust accumulation and moisture? Top-covering packaging equipment helps enterprises build a more complete shipping packaging system

In the past, many companies still needed to manually place plastic film to cover the top of the goods after wrapping them around to prevent moisture, dust, and falling objects from damaging them during transportation or storage. However, this manual laminating method has low efficiency, poor standardization, and poor consistency, and it is difficult to meet the needs of high-frequency shipments and automated circulation. Especially in industries such as food, chemicals, paper products, building materials, and home appliances, where product stacking heights are high and pallet values are high, top-layer protection is particularly critical. At this time, the application of top-wrapping and packaging equipment has become an ideal choice for more and more companies to open up a closed packaging loop and improve transportation safety.

Top-wrapping and packaging equipment, also known as automatic laminating devices or top laminating and wrapping systems, has the core function of automatically and accurately covering the cut PE film or CPP film and other high-toughness films on the top of the pallet goods, and cooperates with subsequent wrapping or packaging actions to form a closed protective structure for the entire pallet of goods. This type of equipment is generally deployed in front of the wrapping station of the automatic packaging line or integrated with the wrapping machine to realize the full process of automatic identification of pallet in place, automatic film pulling, positioning, cutting and film removal, etc., completely replacing manual labor, ensuring that the top film is posted flat, not biased, and not overlapping, greatly improving packaging efficiency and standardization.

Take a large dairy company as an example. Its export orders are mostly shipped by pallet full box. Because the products are sensitive to temperature and humidity, in the past, each pallet of goods needed to be manually filmed by a dedicated person before wrapping and packaging. The on-site personnel's operation is cumbersome and the process connection is slow. There is often a pile of shipments during peak hours, and the film laminating standards are difficult to unify, which affects the packaging appearance and factory image. Since the introduction of the top-covering packaging equipment, the company has merged the film laminating and wrapping processes. Before the film wrapping begins, the equipment automatically completes the precise posting of the top film. The whole action takes only about 5 seconds, which greatly improves the delivery rhythm. At the same time, the top film alignment accuracy is higher than that of manual operation, the packaging aesthetics is significantly improved, the number of on-site packaging stations is reduced by half, the packaging line is smoother, and customer delivery satisfaction continues to improve.

This equipment control system mostly uses PLC and touch screen operation, supports one-button start and stop, parameter adjustment, automatic reset, alarm prompts and other functions, which is convenient for on-site operators to quickly get started. Some models support communication with the upper system, and can be linked with the palletizing line, conveyor line, and film wrapping machine to form an automatic packaging line, realizing a closed-loop automated shipping process of "stacking and sealing, sealing and wrapping" for pallets.

Compared with the traditional manual covering method, the automatic covering packaging equipment not only improves the overall packaging efficiency, but more importantly, it ensures the consistency of packaging standards and the integrity of the top packaging. Especially in the on-site environment where the stacking height is inconsistent and multiple specifications are shipped in parallel, the equipment can automatically identify and adapt according to the sensing signal without human intervention, significantly reducing the packaging deviation and potential quality risks caused by manual differences.
