Whether you are a small business owner or a purchasing manager in a large enterprise, this guide will help you make informed decisions about shrink wrapping machines.
What Is a Машина для упаковки в термоусадочную пленку?
A shrink wrapping machine is a kind of packaging equipment that uses heat to shrink plastic film and adhere to the product or product combination, forming a tight protective seal. The film can precisely conform to the shape of the product, realize the functions of dustproof, moistureproof and tamper-proof, and at the same time clearly display the appearance of the product.
Unlike traditional packaging methods, shrink packaging can reduce material waste and can be adapted to a variety of product shapes and sizes. Hualian’s shrink wrapping equipment covers from compact manual models suitable for small batch production to high-speed industrial-grade shrink wrapping machines suitable for mass production. The core design goal of all equipment is to have a stable output and high-quality packaging. The core component of most shrink packaging systems is the shrink wrapping tunnel machine, which is a heating chamber that triggers the shrinkage of the film to make the packaging stick to the product.
How Shrink Wrapping Machines Work (Step-by-Step)
Although there are differences in the operation details of different types of shrink packaging machines, all devices follow the core five-step workflow. Hualian equipment achieves a balance of efficiency and reliability by optimizing each link:
Step 1: Product Loading
The process begins by placing the product on the conveyor belt or platform of the equipment. For manual models such as the Hualian BSF-5540 manual L-shaped sealing and shrinking packaging machine, this step is completed manually; The automatic equipment will transport the product to the designated position through the automatic feeding device, reducing labor costs. The conveyor belt of Hualian can be flexibly adjusted to adapt to various product sizes from small bottles to large industrial parts.
Step 2: Film Wrapping
Next, the product is wrapped in thermally sensitive shrink film (such as POF, PVC, PE). The Hualian Semi Automatic Sleeve Sleeve Sealing and Shrink Wraving Machine for Bottle will wrap the pre-cut film on the outside of the product; The L-type sealing and cutting machine folds the film around the product, forming a tight “envelope-like” package. The choice of film should be based on the weight, shape, and storage requirements of the product – Hualian’s professional team will provide customized film recommendations for various applications.
Step 3: Heat Sealing & Cutting
After the product is wrapped, it enters the sealing workstation, and the heating knife seat will seal the edge of the film, forming a closed package. At the same time, the equipment will cut off the excess film to ensure that the packaging is neat. Hualian HWS-50C high-speed automatic side sealing machine and other high-speed models adopt precision sealing technology, which can achieve a firm and uniform sealing effect without damaging the product or film. This step is crucial in preventing the film from tearing during the shrinkage process.
Step 4: Film Shrinking Inside the Shrink Tunnel
The sealed packaging enters the shrink wrapping tunnel machine – a heated chamber with controlled temperature and airflow. The Hualian BS-AG heat shrink packaging tunnel machine heats the film evenly with circulating hot air, triggering the molecular shrinkage of the film. The film will closely adhere to every contour of the product, forming a perfect wrapping. The equipment temperature can be adjusted to adapt to different film types, and the Hualian tunnel machine is equipped with a digital control system to achieve precise temperature control.
Step 5: Cooling and Final Finishing
After the packaging leaves the shrink tunnel, it will pass through the cooling area (natural cooling or forced air cooling) to shape the film. This step can prevent the film from stretching or wrinkling during cooling, resulting in a smooth and professional packaging effect that protects the product and enhances visual appeal. The Hualian Economic Automatic Shrink Wrap Machine integrates an in-built cooling system, making this finishing process more efficient.
Key Types of Shrink Wrapping Machines
Hualian provides a variety of shrink wrapping machinery to meet the specific needs of different industries and production capacity. The following are the most popular models, each designed for a specific application scenario:

Shrink Film Types and How to Choose
The right shrink film is just as important as the shrink wrapping machine – the compatibility of the film and the equipment is the key to achieving the best packaging effect. HuaLian’s shrink wrapping equipment can be adapted to three main types of film, each type of film has its own advantages:
POF Shrink Film: Polyolefin (POF) film is the most widely used type, suitable for food, cosmetics, electronic products and other fields. It is tasteless and odorless, has high transparency, and can clearly display product details.The POF film has uniform shrinkage and strong tearing resistance, and can be used in a wide temperature range (120-150°C), and can be matched with most Hualian equipment.At the same time, POF film is recyclable, which is in line with the trend of sustainable packaging.
PVC Shrink Film: The cost of polyvinyl chloride (PVC) film is low, and it has good shrinkage effect on lightweight products. It is often used in products such as bottles, discs, small packaging boxes, etc. However, when PVC is heated, it releases gases, so it needs to be paired with equipment with ventilation functions (such as the exhaust system of Hualian BS-AG tunnel machine). Due to the risk of chemical migration, PVC film is not recommended for use in food contact packaging.
PE Shrink Film: Polyethylene (PE) film is durable and resistant to puncture, designed for heavy or irregular products such as industrial parts and furniture. Its tensile strength is high, and it is suitable for use with industrial shrink wrap machines such as HWS-50C.PE film requires a higher shrinkage temperature (160-220°C) and is often used for pallet packaging and packaging of large items.
Hualian experts suggest that the thickness of the film should match the weight of the product – heavy products should use thicker films;At the same time, it is necessary to make comprehensive decisions in combination with the storage environment).
