Professional Heat Shrink Bag Manufacturing Factory
Deeply cultivating the field of heat shrink bag manufacturing for 20 years, we have stable mass production capacity and a comprehensive quality control process, the monthly output can reach 25 tons. depending on the packaging application of different products, flexible customization the material, thickness, size, and printing pattern of heat shrink bags.
For batch packaging applications, we can base on product size and packaging requirements, customize heat shrink bags with different thicknesses and material structures. The product shrinks evenly, fits tightly, and has a smooth and firm seal, it can effectively reduce problems such as cracking, leakage, wrinkling, and transportation damage, help customers reduce rework rates and packaging losses.
We provide one-stop customization services and can customize heat shrink bags according to your needs.
Why Are Our Heat Shrink Bags so Excellent
Based on the product shape, size, and packaging method match the vertical and horizontal contraction ratios, after heating the bag body more uniform fitting, reducing wrinkles, warping, and local looseness issues.
According to the pressure bearing capacity of paper boxes, bottles, trays, and soft products adjust the contraction force, while maintaining the packaging fit, reduce the risk of product deformation or label wrinkling due to compression.
Regarding the heat shrinkage process continuous tensile force generated optimize the edge sealing strength, after heating the bag not prone to issues such as edge breakage, seal cracking, package leakage, and loose packaging.
For products with sharp corners, hard edges, and high weight, we adopt PET high-strength structure or PVC flexible shrinkage structure, and optimize the thickness and performance of the membrane material, improve puncture and tear resistance.
Tamper-Proof Design
After being heated, the heat shrink bag can tightly wrap around bottle caps, boxes, or the entire product, and form at the opening a continuous and complete sealing protective layer. if consumers or warehouse personnel need to open the packaging, the bag must be torn, cut open, or damaged, packaging usually cannot be restored to the original state, therefore, it is possible to quickly determine the product has it ever been opened, replaced, or touched. This design is suitable for cosmetics, food boxes, drug packaging, electronic products, gift sets, and bottled products, helps to improve the integrity of shelf display and consumer trust in the product.
Tamper-Proof Design
Our heat shrink bags strictly follow the production is carried out through actual packaging and heat shrinkage processes, in terms of material structure, size specifications, thickness, shrinkage rate, and sealing strength, etc maintain stability and consistency, ensure each batch of products uniform shrinkage, smooth fit, and easy packaging. By optimizing the material formula and heat sealing performance, can effectively reduce problems such as uneven shrinkage, wrinkles, cracked seals, and transportation damage, make the packaging tighter and more secure, simultaneously improve the packaging yield and appearance consistency of finished products.
Optimize Production Configuration to Ensure Efficient Order Delivery
As a professional manufacturer of heat shrink bags in China, we are committed to providing wholesalers, brand customers, and packaging purchasers provide stable and reliable bulk customization services. relying on a mature production system and rich export experience, we can cover the stages of product proposal, sample confirmation, large-scale production, quality inspection, and export delivery, etc, help clients shorten communication cycles, improve procurement efficiency, and ensure that order progress and product quality are more controllable.
We have a comprehensive production system for heat shrink bags, equipped with 4 printing lines, 2 composite lines, and multiple bag making production lines, can be based on flexible arrangement of production capacity based on order quantity, material structure, size specifications, and printing technology. Whether it’s new product sampling, small batch restocking, or large-scale procurement, we can all provide stable production support, ensure heat shrink bags uniform size, firm sealing, uniform shrinkage, and smooth fit, reduce batch differences, provide for customers continuous and reliable supply guarantee.
Heat Shrink Bag Application Solutions
For bottled beverages, boxed foods, and food combination packaging, based on the product size, weight, and heat shrink equipment parameters, customize bag size, thickness, and shrinkage performance, reduce packaging wrinkles, seal cracking, and loose packaging during transportation.
Applicable to book, brochure, card, instruction manual, tissue and paper product set. Transparent heat shrink packaging can maintain the product is clean and reduces dust, moisture, and edge wear during storage and transportation.
Suitable for retail packaging of electronic product outer boxes, accessory sets, small appliances, and digital products. Heat shrink bags can help secure the outer packaging, reduce storage and transportation processes dust, scratches, and loose packaging issues that have occurred.

PET：
PET heat shrink bags have features such as high transparency, good glossiness, strong stiffness, and stable shrinkage and bonding effect, can clearly display the appearance of the product. After material shrinkage flat and tight, not easily prone to significant wrinkles, suitable for bottled products, gift boxes, daily necessities, and combination packaging.
PVC：
PVC heat shrink bags have the characteristics of low shrinkage temperature, easy processing, good flexibility, and relatively low cost, can quickly fit products of different shapes. Applicable to packaging for daily necessities, stationery, hardware, gifts, and general retail products.
Customer Feedback on Product Use
MC adjusted the width, length, and thickness of the bag according to our product specifications. The bonding effect after the sample is very good, and it also reduces excess packaging materials.
JasonThe toughness and sealing performance of MC heat shrink bags are relatively stable, and there are no obvious damage problems during the heat shrink, packing, and transportation processes.
Jamie
No, the shrinkage rate needs to match the shape of the product and packaging equipment. The shrinkage rate is too high, may cause damage to the bag body May cause damage to the bag body the shrinkage rate is too low, There may be loose packaging. Choose appropriate longitudinal and transverse shrinkage rates, more important than simply pursuing high shrinkage rate.
Heat shrink bag after heating vertical and horizontal contraction will occur, directly use ordinary printed documents may cause Logo、 The proportion of text or patterns is distorted. Before printing, it is necessary to follow pre deformation treatment is carried out on the actual shrinkage direction and shrinkage rate of the material, make the heat shrunk pattern as close to the design effect as possible.
Not always, increasing thickness can improve strength and puncture resistance, but it may also increase costs and reduce shrinkage speed, and it affects the softness of the packaging.The thickness should be based on the product Determination of weight, corners, transportation methods, and shelf display requirements, instead of the thicker the better.
