Working principle of fully automatic stretch film packaging machine (thermoforming vacuum packaging machine)
The working principle of the fully automatic stretch film packaging machine (thermoforming vacuum packaging machine) is to stretch the lower film in the forming studio, load the package into the formed lower mold cavity, then perform vacuum or vacuum inflation in the vacuum sealing studio, and heat-seal the upper film with the lower film, and then divide the package through the cross-cutting knife system and the longitudinal cutting knife system. Finally, the finished package will be transported to the next process along the conveyor belt, and the remaining waste film material will be recycled by the waste film winding system.
The thermoforming vacuum packaging machine must use a forming mold. After the lower film enters the forming studio, it is formed into the shape of the container through heating and vacuum negative pressure stretching and other technologies, and the package is loaded into the formed lower mold cavity, and finally the package is sealed. The size and shape of the lower film are completely determined by the forming mold. We will design the mold according to customer needs and product characteristics.

What types of plastic packaging materials can be used with thermoforming vacuum packaging machines?
There are many factors that you need to pay attention to:
1. The shape of your product
2. The size of your product
3. The storage environment of your product (humidity, temperature)
4. Packaging type: vacuum packaging
Generally speaking, thermoforming packaging machines require two rolls of film, one roll as the bottom forming film and the other roll as the top sealing film.
While the top sealing film is always thinner and more flexible, the bottom forming film can be rigid or flexible.
Thermoforming films can generally be divided into two types: low-temperature films and high-temperature films.

Low-temperature films
A. High barrier films
Top sealing films: (thickness range 70μm-100μm, EVOH not less than 5μm)
BOPET (BOPP, BOPA)/INK/EVOH co-extruded film
Co-extruded film with the same structure as the bottom film
BOPET (BOPP, BOPA), EVOH co-extruded film
Polyester film (BOPP)/ink/PVDC11/PE
PP, PVDC, PE co-extruded cast film
B. High barrier film
Bottom forming film: (thickness range 100μm-280μm, EVOH layer thickness ratio is usually 8%-10%)
PP/PA/EVOH/PA/PE blown or cast
PA/EVOH/PA/PE blown or cast
CPP/PVDC20/PE
PP, PVDC, PE co-extruded cast film (PVDC layer thickness ratio is 10%)
C. Medium barrier film
Top sealing film: (Thickness range 70μm-100μm)
PA/PE/PA/PE blowing or casting (used when nylon content is low, PA layer thickness ratio is 20%)
BOPA/ink/PE (main structure) or BOPET/INK/EAE co-extruded film
Bottom forming film:
PA/PE/PA/PE blowing or casting (PA layer thickness ratio 20%-40%) or PP/PE/PA/PE

High temperature film
A. medium resistance top film: (thickness range 70μm-100μm)
PP/PA/PP blowing or casting PA content 20%-25% (usually replaced by composite structure because it is easy to stick to the knife during packaging)
BOPA/INK/RCPP or BOPET (BOPP)/PAP co-extruded film
B. medium resistance bottom forming film: (thickness range 100μm-250μm)
PP/PA/PP or PA/PP/PA/PP blowing or casting PA content 20%-40% (e.g. egg vacuum packaging PA content is 35%-40%)
C. High barrier
Top sealing film: (thickness range 70μm-100μm)
BOPP/ink/PVDC11/RCPP
Bottom forming film
RCPP/PVDC20/SCPP
In addition to plastic materials, are there other types of materials that can be used in the machine?
Yes, there are two other materials that can be used in thermoforming vacuum packaging machines.
The first: aluminum foil roll. Aluminum foil has high strength and barrier properties.
The second: dialysis paper and plastic. This type of packaging material is specially designed and produced for medical devices, such as bandages, gauze, medical protective clothing, medical gloves, medical masks, N95 masks, swab covers, etc.
The upper sealing film is TYVEK dialysis paper, and the lower forming film is a peelable PA/PP/PE film. Suitable for sterilization methods such as ETO ethylene oxide, high temperature hot steam, and gamma ray irradiation.
Use, maintenance and care of packaging machines
1. The vacuum pump of the equipment should be replaced with oil every 3 months to keep the oil level at about 3/4. New equipment and equipment that packages liquid products should determine the time and frequency of oil replacement according to the situation. It is recommended to use special oil for vacuum pumps.
2. Lubricate the chain with oil every week, lubricate the main lifting system with butter (and check whether the screws of the lifting system are loose), oil the bearing joint butter cup on the cylinder lifting shaft every 15 days, and fill the lifting system guide block with butter once a week to ensure the normal operation of the equipment.
3. Regular maintenance of the cylinder ensures the integrity of the equipment. Check and handle the pneumatic valves and solenoid valves of the equipment once a month.
4. The equipment should be fully overhauled every 3 months, including the equipment fixing screws and electrical fixing screws, and the filter in the vacuum pump suction port should be cleaned of debris every 3 months to prevent the vacuum from failing to meet the qualified standards. (Cleaning can be carried out at an appropriate time according to your own production needs)
5. When the machine is out of service for more than one week, the longitudinal cutting knife and the cross-cutting knife should be properly coated with vegetable oil to ensure its use effect.
304 Stainless steel frame structure
1. The structure has high strength and corrosion resistance. The screw holes in each fixed position are processed by high-precision laser at one time to ensure the accuracy of assembly and make the whole machine run smoothly.
2. More expandability, when the packaging form needs to be upgraded, relevant parts can be added at any time according to the packaging requirements.
Four-axis linkage lifting device
