First verify applicable objects
Trays, base boards, or support materials suitable for skin packaging; dimensions, breathability structure, surface, and heat seal area confirmed per actual sample
Vacuum Skin Packaging and Contour Forming
Vacuum Skin Packaging Machine
Heated skin film is drawn around the product under vacuum and sealed to a tray or board. This route differs from MAP, standard tray lidding and vacuum pouches. Validate appearance, seal, trimming, cold-chain and transport with the actual product, board or tray and skin film.
Actual equipment footageSkin film contour conformityParameters confirmed per project
Factory equipment photos
Actual equipment photos from the factory. Confirm the final configuration with the containers, product, sample trials and agreed equipment scope.
First see actual working conditions
Product contour, base board, and skin film must be tested as a set
Please provide product, tray or base board, skin film, target appearance, leak or peel standards, target cycle time, and site conditions.
Packaging materials and process must match
Skin film and tray or base board materials must match; stretch, forming, barrier, and heat seal layers verified per sample; product feeding, skin film heating, vacuum forming, sealing to base material, cooling, optional trimming and output
Optional modules are not standard
Optional automatic feeding/unloading, trimming, coding, inspection, rejection, cooling, and downstream conveying.
Parameters confirmed per project
Please provide product, tray or base board, skin film, target appearance, leak or peel standards, target cycle time, and site conditions.

Information recommended before quotation
The more complete the samples, packaging materials, and site information, the easier it is to determine equipment route, changeover scope, and line integration boundaries.
Configuration reference
- Product contour, sharp corners, and height verified through actual skin packaging samples
- Trial the actual skin-pack film with its tray or backing board to confirm film forming around the product and heat-seal compatibility.
- Automatic feeding/unloading, trimming, inspection, and downstream conveying are optional modules
- Confirm vacuum, heating conditions and actual cycle time by trialling the product, tray or backing board and skin-pack film together.
Prepare for selection
- Product sample, dimensions, height, sharp corners, liquid leakage, and heat resistance
- Tray or base board sample, material, breathability, and heat seal area information
- Skin film sample, width, stretch, barrier, and heat seal layer information
- Target appearance, seal standards, target cycle time, and site layout

Key Parameters
Capacity and Cycle Time
Confirmed based on loading method, film heating forming, vacuum, sealing cooling, and trimming output. Actual capacity is confirmed by project trials.
Automation Scope
Skin forming and sealing; automatic feeding/unloading, trimming, inspection, coding, and downstream conveying optional per project
Applicable Containers or Packaging
Trays, base boards, or support materials suitable for skin packaging; dimensions, breathability structure, surface, and heat seal area confirmed per actual sample
Applicable Products
Fresh meat, seafood, cooked food, parts, or other products requiring contour display; specify height, sharp corners, liquid leakage, and heat resistance
Packaging Materials and Consumables
Skin film and tray or base board materials must match; stretch, forming, barrier, and heat seal layers verified per sample
Basic Process
Product feeding, skin film heating, vacuum forming, sealing to base material, cooling, optional trimming and output
Tooling and Changeover
Replace or adjust support, tooling, film path, and trimming structure according to tray or base board dimensions, product height, and film width
Power, Air Supply, and Layout
Confirm equipment dimensions, power, air supply, maintenance space, and upstream/downstream interfaces based on vacuum system, film heating, forming sealing, cooling, trimming, and optional conveying
Steps from sample confirmation to delivery
Confirm product contour, sharp corners, height, tray or base board structure.
Observe heating stretch, conformity, wrinkles, film breakage, and final appearance.
Check base material seal, peel or leak standards, and trimming range.
Accept according to agreed product, material, appearance, cycle time, and changeover requirements.
Common configuration routes
Compare Skin Packaging, Vacuum Bagging, and Tray Sealing
Vacuum skin, MAP, thermoforming vacuum and vacuum pouches have different packaging goals, films, cavities and loading methods; vacuum alone does not make them equivalent.
Vacuum Skin Packaging
Film conforms to product contour and seals to base material, emphasizing display and fixation.
Vacuum Bagging
Product is placed into a pre-made bag, vacuumed, and sealed; packaging form and equipment differ.
Tray Lidding and Sealing
Film mainly seals the rim of the tray, not required to conform to product contour.

Frequently Asked Questions
Are all trays suitable for skin packaging?
Not necessarily. The material, breathability, flatness, and heat seal layer of the tray or base board affect forming and sealing, and need to be tested together with the skin film.
Will sharp products puncture the skin film?
There is a risk. Sample testing is required based on sharp corners, product height, film stretch, and forming conditions; adjust product placement or packaging structure if necessary.
Send samples and requirements
First confirm samples, packaging materials, and process, then determine final configuration
Send product samples or dimensions and weight, highest points and sharp-edge photos, purge, tray or board structure, skin-film data, appearance and seal criteria, cold-chain temperature, transport, changeovers and downstream labelling or case packing.
