Route comparison
- Tablets, capsules, or regular small parts that can be oriented and loaded into individual blisters.
- Bottom film forming, product loading, lidding film sealing, indexing, and cutting can be completed continuously.
- Blister depth, loading orientation, missing item inspection, and layout all need to be sampled according to the product.
- When the product shape cannot be stably placed into blisters or materials are not yet determined, it is not advisable to freeze the mold.
- Fully automatic blister packaging machine, optionally connected to automatic feeding, vision inspection, marking, and cartoning.
- Products that require in-line cavity forming from the bottom film, loading, film feeding, vacuum sealing, and cutting.
- Multiple processes from roll stock to individual finished products can be completed on a continuous production line.
- Layout, forming cooling, loading time, hygiene cleaning, and cutting determine the entire line configuration.
- For small batches with many specifications and unacceptable mold change costs, other packaging forms should be compared.
- Stretch film thermoforming vacuum line with manual or automatic loading and optional gas flushing.
- Fresh meat, seafood, cooked food, or parts that require the film to conform to the contour and be fixed to a tray or base board.
- Skin film can form a highly presentable packaging shape around the product contour.
- Product height, sharp corners, liquid seepage, base board breathability, and film stretching all need to be confirmed with actual samples.
- When the product or base board cannot withstand the process conditions, the skin packaging route should not be chosen solely based on appearance goals.
- Vacuum skin packaging machine, optionally configured with loading/unloading, trimming, inspection, and downstream conveying.

Core process
Sample details
Product samples and dimensions, weight, sharp corners, and surface condition are used to evaluate forming cavities, skin packaging effect, and packaging protection boundaries.
Provide product samples, dimensions, height, weight, sharp corners, and surface condition.Base material, lidding film, top film, skin film, tray, or base board must be sampled according to the target combination; they cannot be directly substituted across material routes.
Provide samples of base material, lidding film, top film, skin film, tray, or base board.The finished layout, cavity depth, contour, and cutting method determine mold arrangement and trim path; they should be checked against the target finished product drawing and samples.
Specify the finished layout, cavity depth, contour appearance, and cutting method.Vacuum, gas flushing, barrier, leakage, and peel targets should be defined separately to select the process and establish finished product acceptance methods.
Specify vacuum, gas flushing, barrier, leakage, or peel acceptance targets.Manual or automatic feeding, missing item inspection, and downstream cartoning are different interfaces; the incoming material orientation and delivery scope for each section should be clarified.
Specify manual or automatic feeding, missing item inspection, and downstream cartoning needs.Continuous output, cleaning standards, plant layout, and utilities are used to verify line length, operating space, and auxiliary systems.
Provide stable output, cleaning standards, plant layout, and utilities.Common selection mistakes

Real Customer Questions
For regular small parts that need to be loaded one by one into blisters and sealed and cut, start with the layout, blister depth, and automatic feeding. For food, medical, or industrial products that require in-line forming of cavities from the bottom film, loading, vacuum sealing, and cutting, evaluate a thermoforming vacuum line. For fresh meat, seafood, or parts where the film should conform to the contour and seal to a tray or base board, the vacuum skin packaging route is closer to the goal.
First Determine the Packaging Route
All three routes involve film forming or sealing, but product feeding, cavity source, vacuum goal, cutting method, and finished product use differ; one set of molds or material assumptions cannot replace actual samples.
Regular Small Parts Blister Forming and Sealing Route
Suitable for: tablets, capsules, or regular small parts that can be oriented and loaded into individual blisters. Advantages: bottom film forming, product loading, lidding film sealing, indexing, and cutting can be completed continuously. Limitations: blister depth, loading orientation, missing item inspection, and layout all need to be sampled according to the product. Not recommended: when the product shape cannot be stably placed into blisters or materials are not yet determined, it is not advisable to freeze the mold. Equipment direction: fully automatic blister packaging machine, optionally connected to automatic feeding, vision inspection, marking, and cartoning.
Thermoforming Vacuum Continuous Packaging Route
Suitable for: products that require in-line cavity forming from the bottom film, loading, film feeding, vacuum sealing, and cutting. Advantages: multiple processes from roll stock to individual finished products can be completed on a continuous production line. Limitations: layout, forming cooling, loading time, hygiene cleaning, and cutting determine the entire line configuration. Not recommended: for small batches with many specifications and unacceptable mold change costs, other packaging forms should be compared. Equipment direction: stretch film thermoforming vacuum line with manual or automatic loading and optional gas flushing.
Vacuum Skin Packaging Contour Display Route
Suitable for: fresh meat, seafood, cooked food, or parts that require the film to conform to the contour and be fixed to a tray or base board. Advantages: skin film can form a highly presentable packaging shape around the product contour. Limitations: product height, sharp corners, liquid seepage, base board breathability, and film stretching all need to be confirmed with actual samples. Not recommended: when the product or base board cannot withstand the process conditions, the skin packaging route should not be chosen solely based on appearance goals. Equipment direction: vacuum skin packaging machine, optionally configured with loading/unloading, trimming, inspection, and downstream conveying.
Recommended Equipment Route: Product and Material Forming Test
Actual samples are used to confirm forming depth, product contour, and material suitability boundaries.
Recommended equipment route: select the main process according to the finished product target
Product cavity entry, vacuum sealing or contour skin packaging correspond to different main processes.
Recommended equipment route: check sealing and finished product appearance
Inspection stations should be set up around missing product, sealing and appearance standards.
Recommended equipment route: connect to cartoning or finished product conveying
The downstream format is determined by finished product size, cleanliness requirements and case packing method.
Common questions
Is blister packaging only suitable for pharmaceuticals?
No, regular small parts can be evaluated as long as they can be stably placed into blisters and meet material requirements.
Can the thermoforming vacuum line have automatic feeding?
It can be evaluated based on the product, but the feeding method, orientation, and inspection need to be configured separately.
Does vacuum skin packaging always require a tray?
Not necessarily; a suitable base board or support material can also be evaluated.
Can the same film be used for all three routes?
It cannot be assumed to be universal; forming, heat sealing, barrier, and stretching requirements need to be verified separately.
Can products with sharp corners be skin packaged?
It is possible to first make samples to evaluate film material, placement, and local protection; it cannot be judged by size alone.
Can the machine be selected without a finished layout?
Routes can be compared first, but the final mold and cycle time need to be confirmed together with the product, materials, and layout.
