Dongguang County Donghui heat shrinkable Film Co., Ltd. is a professional Chinese Vacuum heat shrinkable packaging manufacturers and Chinese Vacuum heat shrinkable packaging (Vacuum heat shrink packaging) suppliers, dedicated to providing high-quality vacuum heat shrink packaging products for the food, pharmaceutical, electronic, hardware and other industries, covering wholesale (wholesale), customized production and vacuum packaging solution design services The product price is both cost-effective and competitive. Regular specification orders can be delivered within 5 to 7 days, precisely meeting customers' dual packaging requirements of "vacuum preservation + shrink fixation" for the product. The company has a standardized production base covering an area of over 8,000 square meters, equipped with 5 fully automatic vacuum heat shrink film production lines. It adopts multi-layer co-extrusion equipment imported from Germany and vacuum sealing performance testing instruments. Vacuum heat shrinkable packaging materials with a thickness of 0.03mm-0.12mm and a width of 50mm-1500mm can be produced, with an annual production capacity of up to 2,200 tons. In terms of raw material selection, we strictly choose composite base materials (such as PE/PA, PE/PET composite films) that comply with the national GB 4806 food contact standards and medical-grade packaging requirements, free of harmful substances like benzene and heavy metals, to ensure that the packaged products are safe and pollution-free. At the same time, a full-process quality control system of "raw material incoming inspection - vacuum degree monitoring during production process - finished product puncture resistance and sealing performance test" was established. Through vacuum leakage test (leakage rate ≤0.1kPa/min) and thermal shrinkage rate test (lateral shrinkage rate 25%-35%), More than 20 indicators such as longitudinal shrinkage rate (8%-12%) and puncture resistance strength test (≥30N) are screened to ensure that each batch of Vacuum heat shrinkable packaging has the advantages of high sealing performance, toughness and uniform shrinkage. It can not only achieve vacuum preservation of products (extending the shelf life of food by 2-3 times), but also closely adhere to the product shape through thermal shrinkage, avoiding product displacement or damage from bumps during transportation.
The Vacuum heat shrinkable packaging of Dongguang County Donghui Heat Shrinkable Film Co., Ltd. has multi-scenario adaptability and functional targeting, and can provide customized solutions according to the product characteristics of different industries. For the food industry, we have launched food-grade vacuum heat shrink packaging, which uses PE/PA high-barrier composite film. It can effectively isolate oxygen, water vapor and odors, and is suitable for packaging products such as meat, seafood, cooked food and nuts. For example, when used for beef packaging, it can achieve low-temperature freezing weather resistance of -40℃. After thawing, the film does not break or stick together, and can clearly display the texture of the meat. Enhance the appeal of the product shelves; For the pharmaceutical industry, we have developed medical-grade vacuum heat shrink packaging that complies with GMP pharmaceutical packaging standards and features excellent chemical stability. It can be used for vacuum packaging of medical devices (such as surgical knives and syringes) and pharmaceutical intermediates, effectively preventing microbial contamination and external environmental interference. For the electronics and hardware industries, we offer anti-static vacuum heat shrink packaging with a surface resistance value controlled between 10^8 and 10^11Ω. It is suitable for electrostatic sensitive products such as chips, circuit boards, and precision hardware accessories. It can not only isolate dust and moisture through vacuum packaging but also prevent static electricity from damaging the products through its anti-static function. Furthermore, our Vacuum heat shrinkable packaging supports diverse customization. The thickness of the film (to adapt to products of different weights), width and length (to adapt to products of different sizes) can be adjusted according to customer requirements. It can also adopt the environmentally friendly water-based ink printing process to print brand logos, product batch numbers, shelf life and other information on the film surface. The printing accuracy reaches 300dpi, the patterns are clear and resistant to friction (friction color fastness ≥ grade 4), and it takes into account the three functions of packaging protection, information identification and brand promotion. At the same time, it supports preforming into bags (such as three-side sealed bags, middle-sealed bags), which is convenient for customers to use directly. Reduce subsequent processing steps.
Dongguang County Donghui heat shrinkable Film Co., Ltd. has provided comprehensive qualification certification endorsement for Vacuum heat shrinkable packaging products, and steadily expanded in overseas market layout at the same time. The company has passed the ISO 9001 Quality Management System certification (to ensure the standardization of production processes and the stability of product quality), ISO 45001 Occupational Health and Safety Management System certification (to ensure the safety of employees' production operations), and ISO 14001 Environmental Management system certification (to achieve environmental protection and emission reduction in the production process). For instance, the recovery and utilization rate of waste gas reaches over 95%, and water resources are recycled. This ensures product quality from multiple dimensions such as production compliance, safety, and environmental protection. In addition, it has obtained the nationally recognized after-sales service certification (GB/T 27922) and the green supply Chain evaluation certificate. Among them, the after-sales service certification guarantees that after customers purchase Vacuum heat shrinkable packaging, You can enjoy free sample delivery (supporting customers to test the packaging effect in advance), vacuum packaging equipment adaptation guidance (providing parameter suggestions for heat shrink machines that match the packaging film), packaging process optimization plans (such as adjusting the vacuum degree and shrinkage temperature according to the characteristics of the customer's products), and other services. If problems such as poor sealing of the film or shrinkage and wrinkles occur during use, Our technical team can quickly solve the problem through online video guidance or on-site service within 48 hours. The Green Supply Chain evaluation certificate proves that our Vacuum heat shrinkable packaging production process complies with green environmental protection requirements. The recyclable rate of the composite base materials used is over 85%, and there is no discharge of wastewater or waste residue during the production process. It complies with the EU RoHS environmental protection standard and the US FDA food contact standard. At present, our Vacuum heat shrinkable packaging has been exported to 16 countries and regions, including Southeast Asian markets such as Vietnam, Thailand and the Philippines (to meet the demands of local food processing and seafood export enterprises). And in European markets such as Germany and France (meeting the high-standard packaging requirements of the local pharmaceutical and electronic industries), with stable quality and customized services, it has become the core partner of vacuum shrink packaging for many foreign trade enterprises
