Vacuum Skin Packaging Machine
The Vacuum Skin Packaging Machine is designed for commercial food processors using tray- or board-based skin packaging. It creates a close-contact pack by securing the product beneath a conforming top film, providing stable product positioning and a clean presentation for retail and distribution.
Vacuum Skin Packaging for Commercial Food Products
The Vacuum Skin Packaging Machine uses a heated skin film and vacuum chamber to form the film closely around the product and seal it to a compatible tray or rigid backing board. The product is positioned on the tray or board inside the chamber, where air is evacuated and the softened film is drawn down over the product surface before sealing.
This vacuum skin packaging process creates a close-contact pack that holds the product securely in position while keeping its shape clearly visible. The result is a clean, well-defined tray- or board-based package suited to products where stable presentation and controlled product placement are important.

Key Advantages of the Vacuum Skin Packaging Machine
Customizable Skin-Pack Tooling
Packaging molds can be customized for different tray or backing-board dimensions, allowing the vacuum skin packaging machine to accommodate a wider range of product sizes and VSP package formats.
Touchscreen Operation and Independent Temperature Control
A touchscreen HMI provides centralized access to operating settings, while a separate digital temperature controller allows heating conditions to be adjusted independently for different packaging requirements.
SUS304 Stainless Steel and Aluminum Alloy Construction
SUS304 stainless steel and aluminum alloy components provide a rigid, corrosion-resistant machine structure designed for repeated use in commercial vacuum skin packaging operations.
Vacuum Skin Packaging Applications
The Vacuum Skin Packaging Machine is designed for food products packed on compatible trays or rigid backing boards, particularly where the product shape and profile need to remain clearly defined within the finished pack. Typical applications include premium meat cuts, seafood portions, raised-profile products, and chilled ready-to-cook foods.
Premium Meat Cuts and Steaks
Suitable for steaks, portioned beef, pork cuts, lamb, meat skewers, and similar premium meat products packed individually on trays or rigid backing boards for retail and commercial presentation.
Fish and Seafood Portions
Common applications include salmon portions, fish fillets, shrimp, scallops, lobster, crab, sea cucumber, and other seafood products packaged in individual skin-pack formats.
Raised-Profile and Irregular Products
Chilled and Ready-to-Cook Food Packs
Suitable for portioned chilled foods, marinated products, prepared ingredients, and ready-to-cook items packed in tray- or board-based formats for retail and foodservice applications.
FAQ About Vacuum Skin Packaging Machine
What is the difference between vacuum skin packaging and standard vacuum bag packaging?
Vacuum skin packaging uses a heated top film that conforms closely to the product and seals to a tray or rigid backing board. Standard vacuum packaging places the product inside a flexible pouch, removes the air, and seals the pouch. The two formats differ mainly in package structure, product presentation, and handling method.
What is the difference between vacuum skin packaging and modified atmosphere packaging?
Vacuum skin packaging removes air and draws the film closely around the product, while modified atmosphere packaging replaces the air inside a sealed tray with a controlled gas mixture. VSP is generally chosen for close-contact presentation, while MAP is selected when a controlled package atmosphere is required.
Can vacuum skin packaging use both trays and backing boards?
Yes. Depending on the tooling and package design, the machine can be configured for compatible trays or rigid skin-pack backing boards. The selected format should match the product dimensions, film structure, and required package presentation.
What type of film is required for vacuum skin packaging?
The machine requires compatible VSP film designed to soften during heating, conform around the product, and seal securely to the selected tray or backing material. Film compatibility should be confirmed with the tray or board structure before production.
Do different tray or backing-board sizes require different molds?
In many cases, different package dimensions require corresponding molds or tooling. The required setup depends on the tray or board size, product footprint, and packaging area, so the range of package formats should be considered when selecting the machine configuration.
Can the machine package products with raised or irregular profiles?
Yes, provided the product dimensions and height remain within the machine and tooling limits. Vacuum skin film can conform around irregular or raised surfaces, but the package design, film properties, and mold configuration should be matched to the product profile.
When should I choose vacuum skin packaging instead of thermoforming packaging?
Vacuum skin packaging is a good choice when the priority is close-contact presentation on a tray or rigid backing board. Thermoforming packaging is better suited to applications that require rollstock package forming and a higher level of automated continuous production.
