Taizy heat shrink wrap machine helps factories quickly seal packaging to create clean, protective, and aesthetically pleasing products. Our integrated system comprises a fully automatic L-shaped sealing machine and a heat-shrink tunnel, capable of sealing 20-40 boxes per minute.
In addition, it provides dust and moisture protection for products, enhancing their durability during transport. Therefore, a heat shrink wrap machine is ideal for products such as food trays, gift boxes, cosmetic boxes, stationery sets, books, sushi boxes, and hardware tool sets.
Key features of this shrink wrapping machine

It features automatic film feeding, waste collection, and high-speed hot air circulation.
- Its sealing blades ensure smooth and clean sealing lines, preventing film scorching and guaranteeing a superior retail appearance for the product. The circulating hot air tunnel ensures uniform heating in all directions, achieving tight glossy shrink packaging, enhancing product value.
- Taizy fully automatic shrink wrapping machine’s conveyor belt width can be adjusted. Its wide sealing frame and large tunnel size support a variety of products, including packaging boxes, food trays, books, cosmetics, and hardware kits.
- Our box shrink wrap machines feature a dedicated safety and energy-saving design with temperature protection and emergency stop functions. Additionally, its insulated tunnel structure helps reduce energy consumption while ensuring safe operation.
Structure and work principle of the heat shrink wrap machine
A complete automatic heat shrink wrap machine consists of two parts: an L-shaped sealing and cutting unit and a heat shrink tunnel.
1. Sealing and cutting machine
The sealing and cutting machine components are responsible for wrapping, sealing, and cutting the film.
Its structure typically includes: an L-shaped sealing blade, a film holder and film feeding system, a conveyor belt, a pressure plate/sealing frame, a waste film collection system, a conveyor belt width adjustment handle, and a control panel (temperature control, sealing time control, power switch, and emergency stop button).
2. Heat shrink tunnel
The heat shrink tunnel provides uniform and controllable heat, allowing the film to tightly shrink and wrap the product.
② Heat Shrink Tunnel (Hot Air Circulation Section)
The heat shrink tunnel provides uniform and controllable heat, allowing the film to tightly shrink and wrap the product.
Its main structural components include: high-efficiency heating tubes, a hot air circulation system, an insulated heating chamber, a heavy-duty conveyor belt, a temperature controller (adjustable from 0–300°C), and a speed controller.
This heat shrink wrap machine operates through the following three major steps:
- Step 1: Place the product on a conveyor belt and enter the sealing area. The shrink film (POF/PVC/PE) is pulled from the film roll, forming a thin film wrap around the product.
- Step 2: When the product reaches the sealing position, the L-shaped sealing blade presses downwards. The film seals tightly along the edges. Excess film is automatically cut and sent to the waste collection system.
- Step 3: The hot air circulates within the shrink tunnel, evenly heating the film, causing it to shrink and conform to the product’s shape. Then the final product emerging from the tunnel has a smooth, firm, and glossy surface with a protective shrinkage effect.

Wide applications of the shrink wrap machine heat sealer
The shrink wrapping machine is widely used in food packaging. It is commonly used for packaging ready-to-eat meals, spices, snacks, and candy boxes, providing dust and moisture protection, hygiene, and safety, as well as strong sealing to prevent the smell of spices from easily spreading.
In addition, this heat shrink wrap machine is also essential in the packaging of gift boxes. The plastic-sealed cosmetic gift boxes, skin care sets, mask boxes, and makeup sets not only prevent scratches and contamination and ensure safe transportation and handling, but also enhance the retail level and maintain the brand image.
Heat-shrink machines are also widely used in the packaging of printed materials. Plastic-sealed books and magazines can effectively reduce paper curling and also prevent dust, moisture, insects, and pests.
How to choose the right heat shrink wrap machine?
Choosing the right machine involves many factors. How can you meet packaging needs while minimizing costs? The following points are crucial to consider when selecting the best shrink wrap machine.
- First, consider the type and size of the product to be packaged. If you need to package small boxes, books, cosmetics, small electronic items, or food trays, then a medium-sized sealing and cutting machine and a medium-sized shrink oven will suffice.
- Choose the level of automation based on your packaging capacity requirements. For small packaging volumes, a semi-automatic machine is suitable. But for large-volume continuous production or assembly line operations, a fully automatic shrink wrapping machine is a more efficient choice.
