JB/T 15781-2026 Food Vacuum Skin Packaging Machine Standard Drafted by Utien Pack

In August 2026, China’s Ministry of Industry and Information Technology has officially approved and issued JB/T 15781-2026 Food Vacuum Skin Packaging Machine, a machinery industry standard drafted with the leadership and technical expertise of Utien Pack. The standard establishes a unified technical basis for the design, manufacture, inspection, acceptance, application, packaging, transportation, and storage of food vacuum skin packaging machines.

Its publication represents an important step for the development of vacuum skin packaging equipment in China. It also recognizes the practical experience that Utien Pack has accumulated through machine research, food packaging applications, production line projects, and customer service in domestic and international markets.

A Clear Technical Basis for a Growing Market

Demand for vacuum skin packaging continues to rise in fresh meat, seafood, cooked food, ready meals, cheese, bakery products, and pet food. The format closely conforms the skin film to the product and its base, helping hold the product in position, control purge movement, protect its appearance, and create a clear three dimensional display. When combined with suitable materials, reliable sealing, and a controlled cold chain, it can also support longer product freshness and more stable distribution.

However, rapid market growth has also created practical challenges. Machine configurations, operating parameters, skin forming performance, and quality evaluation methods have varied among suppliers. Without a unified technical reference, food processors may find it difficult to compare equipment, confirm acceptance requirements, control package quality, or plan maintenance.

JB/T 15781-2026 responds to these issues with a more complete and consistent framework. It defines machine models and product classifications, basic operating parameters, standard working conditions, technical requirements, and test methods for the complete machine. It also specifies requirements for machine nameplates, equipment packaging, logistics transportation, and storage. The standard can therefore serve manufacturers, testing organizations, and food processors throughout equipment development, production, inspection, acceptance, and compliant use.

For food companies, the standard creates a clearer language for technical communication with equipment suppliers. Buyers can use defined items to review machine configuration, compare proposals, prepare factory acceptance testing, and confirm whether delivered equipment meets agreed performance requirements. For manufacturers, it encourages consistent design, documented testing, traceable quality control, and more responsible service. This shared basis can reduce uncertainty during procurement and support better decisions throughout the service life of the machine.

Turning Production Experience into Practical Requirements

An effective industry standard must reflect actual factory conditions. Utien Pack contributed more than a decade of specialized experience in vacuum skin packaging, including applications for steak, chilled meat, seafood, prepared food, cooked products, cheese, and other products with irregular shapes or raised profiles.

The company completed a major domestic technology breakthrough in 2013 and became the first enterprise in China to achieve independent development and practical application of this type of equipment. In 2025, Utien Pack also led the drafting of GB/T 46076-2025 General Technical Requirements for Automatic Vacuum Skin Packaging Machines. These milestones provided a strong technical foundation for its work on the new food packaging machine industry standard.

During the drafting process, Utien Pack drew on machine development records, control system data, food grade manufacturing practices, package testing, and experience from customer production sites. Common challenges from actual operation were translated into clear technical requirements and test criteria. This approach helps ensure that the standard is scientifically rigorous while remaining practical for equipment manufacturers and food factories.

Vacuum Skin Packaging Technology Built for Food Production

Utien Pack designs its food vacuum skin packaging machines around stable vacuum performance, accurate film heating, controlled sealing pressure, reliable skin forming, and consistent operation. Precise control of temperature, vacuum, sealing time, and cycle parameters helps the film conform evenly to the product with fewer bubbles, folds, or unsealed areas.

Busch vacuum pumps provide a stable vacuum source for demanding production. For products with greater height, Utien Pack offers its patented Unifresh® vacuum skin packaging technology. It can closely conform film around product protrusions of 50 mm. This capability is especially valuable for premium thick cut meat in the 30 to 50 mm range, as well as seafood, cheese, and other products that require strong three dimensional presentation and stable product positioning.

Vacuum skin packaging is not limited to one product category. Meat is currently one of its most mature applications, but the technology is also suitable for seafood, dairy products, ready meals, and selected bakery products. Package design, skin film, base material, vacuum level, heating profile, and sealing parameters must be selected according to the product and its distribution requirements. Utien Pack evaluates these factors as an integrated packaging system rather than treating the machine as an isolated unit.

Food Grade Construction and Reliable Control

Food factories need equipment that can support hygiene, frequent cleaning, worker safety, and continuous production. Utien Pack machines use 304 stainless steel and an IP65 protection design. Accessible construction and removable modules help operators clean important areas more efficiently and reduce hygiene risks in wet or oily production environments.

Safety sensors and emergency stop devices protect operators and the production process. Standardized inspection is completed before each machine leaves the factory, and key quality records remain traceable. These measures support the technical, safety, and hygiene principles reflected in the new industry standard.

The control system combines a Siemens PLC and touch screen interface with components from established international suppliers such as Schneider, SMC, and Busch. Multiple production recipes can be stored and selected for different products. Operating data can be monitored during production, while fault warnings help operators identify abnormal conditions quickly. Servo drive technology supports accurate film feeding and positioning, contributing to stable package appearance and efficient material use.

From Individual Machines to Complete Packaging Lines

Food processors have different products, output targets, workshop layouts, labor conditions, and automation plans. Utien Pack can configure semi automatic equipment for flexible production or fully automatic continuous systems for larger factories. The packaging machine can also connect with loading, filling, weighing, labeling, coding, inspection, and conveying systems to form an integrated production line.

With more than 30 years of experience in packaging equipment, Utien Pack has served more than 3,000 food companies and delivered machines and services to over 50 countries. Its service covers project evaluation, package testing, equipment selection, line planning, installation support, operator training, and long term maintenance guidance. This experience allows the company to adapt each solution to actual food products and production conditions.

Standards Support Better Equipment and Safer Food Packaging

The approval and publication of JB/T 15781-2026 is both an industry recognition and a responsibility for Utien Pack. A unified standard gives machine manufacturers clearer development targets, helps food processors evaluate equipment with consistent criteria, and supports more transparent quality control across the market.

Utien Pack will continue to use the standard as an important reference for research, manufacturing, testing, and service. The company will further develop vacuum skin packaging, modified atmosphere packaging, and thermoforming packaging technologies while improving freshness protection, intelligent control, production efficiency, and line integration.

By combining technical innovation with practical standards, Utien Pack aims to support the responsible development of food packaging equipment and help processors deliver fresher, safer, and better presented products to consumers worldwide.
