DR - Heat Shrink Packaging Machine

I. Product Overview

The power of a PE shrink machine is generally relatively high, ranging from 20 to 40 KW. The set temperature is also relatively high, typically between 180° and 220°. The settings vary depending on the thickness of the material, the speed of the conveyed products, the volume of air flow, and the temperature level. For products that are not heat-resistant, a lower temperature and thinner shrink film can be used. If the shrink film is thick, the temperature needs to be increased and a more powerful shrink machine should be selected. If the speed of the conveyed products is increased, the temperature should be raised accordingly; conversely, it should be lowered. If the volume of air flow is increased, the temperature should be reduced accordingly; conversely, it should be raised. The power of a POF or PVC shrink machine is generally between 5 and 20 KW, and the temperature is typically set between 140° and 160°. The adjustments are basically the same as those for a PE shrink machine. 

II. Core Selling Points

Integrated sealing, cutting and shrinking process, single-line operation with reduced manpower, and stable cycle time. 

The hot air circulation channel is optimized to ensure that the material is smooth and wrinkle-free after shrinking. 

Intelligent PID temperature control and multi-segment curves are suitable for different membrane materials and heights. 

The modular quick-release heating components and conveying system have a short maintenance downtime. 

Supports non-standard sizes, turning lines, and online connection with labeling, inkjet coding, weighing, and scanning. 

III. Applicable Industries and Products

Food and Beverage: Mineral water, canned drinks, boxed beverages, snack gift boxes. 

Household and personal care products: tissue box, body care set, cleaning supplies combo. 

Electronics and appliances: Small household appliances outer boxes, accessory trays, cable products. 

Stationery and books: Book collections, stationery gift boxes, e-commerce shipping packaging. 

Pharmaceuticals and hardware building materials, plastic products and other scenarios. 

IV. Working Principle

The conveying system delivers the products into the sealing and cutting area to complete the film material wrapping and sealing and cutting. 

The product enters the heat shrinkage channel, and the circulating hot air makes the film material evenly heated and tightly adhered. 

After emerging from the oven and passing through the cooling and shaping section, a tight and smooth contracted appearance is achieved. 

V. Main Functions

Automatic feeding, alignment and bag pushing, supporting single-row and multi-row bundling. 

Automatic deviation correction and film material tension control reduce wrinkles and waste. 

Material shortage shutdown, material jam alarm, and over-temperature protection ensure continuous operation. 

One-click call of formula parameters for quick production changeover. 

Optional modules include printing, labeling, inkjet coding, weighing, and traceability through scanning.
