Huangjing stretch film vacuum packaging machine, medicinal cleaning, steaming and packaging line

Huangjing stretch film vacuum packaging machine, medicinal cleaning, steaming and packaging lineEquipment Introduction:

Stretch film vacuum packaging machine is an automated equipment that integrates film forming and vacuum preservation functions, mainly used for vacuum or modified atmosphere packaging of products in industries such as food, medicine, and electronics. Its core function is to shape the plane film material into a specific container through stretching molding, and then seal and keep fresh through vacuum treatment.

core functionality

Stretch forming: Softening and shaping a thin film into specific shapes (such as square boxes, round boxes, etc.) through a heating plate and mold, suitable for stretch forming of soft films, hard films, and semi hard films.

The fully automatic stretching vacuum packaging machine is a vacuum or inflatable packaging equipment used for products in industries such as food, medicine, and hardware. It is suitable for sealing materials such as meat products, seafood, fruits and vegetables, medical equipment, etc. Its core function is to extend product shelf life and improve packaging efficiency through vacuum packaging.

Huangjing stretch film vacuum packaging machine, medicinal cleaning, steaming and packaging lineThe equipment adopts Mitsubishi programmable controller and large touch screen as the main control system, equipped with American high-sensitivity photoelectric sensors to achieve precise color film positioning, and equipped with German original vacuum pump to ensure stable operation at high vacuum degree. Support quick replacement of composite molds, compatible with stretching and forming of various materials such as soft film and hard film, and built-in corner waste recycling system to maintain a clean production environment. The device also integrates automatic coding, fault alarm, and maintenance prompt functions, and adapts to different packaging speed requirements through frequency conversion or servo drive systems.

Core features and advantages

1. Fully automated:

The entire process from film feeding, stretching and forming, product conveying/loading, vacuuming, sealing, cutting to finished product output does not require manual intervention (or only a small amount of manual material placement).

Greatly saving labor costs and improving production efficiency, especially suitable for large-scale production.

2. Use stretch backing film:

Unlike packaging machines that use prefabricated pallets, it uses a rolled flat plastic base film (usually made of PP or PE material).

Soften by heating inside the machine, and then precisely stretch the bottom film into a tray that matches the shape of the product using a mold (usually vacuum formed or pressure formed). This is called hot forming.

Advantage:

Save material costs: The thickness of stretch film is usually thinner than that of prefabricated pallets, and the material utilization rate is high, without the waste of scraps from prefabricated pallets.

Good packaging adhesion: The mold can be made according to the shape of the product to achieve tight and beautiful body to body packaging, reduce internal space, save gas (such as inert gas), and improve protection.

Reduce inventory: Only store roll film, no need to store prefabricated pallets of multiple specifications.

3. Vacuum/Modified Atmosphere Packaging:

After covering with film, it can effectively remove the air inside the packaging cavity.

Pure vacuum packaging can be used, or a specific ratio of mixed gases (such as nitrogen and carbon dioxide) can be filled after vacuuming, known as modified atmosphere packaging, which effectively inhibits microbial growth and oxidation, significantly extending the shelf life of food and other products.

4. High sealing performance:

By heating, the upper film (usually a composite film with barrier properties) is firmly fused and sealed with the edge of the formed bottom film.

Ensure that the internal environment of the packaging is isolated from the outside world to prevent air leakage, seepage, or contamination.

5. High efficiency and high output:

Continuous production with fast running speed (can complete several to dozens of packages per minute, depending on mold size and number of workstations).

It is an ideal choice to replace traditional manual or semi-automatic vacuum packaging, with a significant increase in production capacity.

6. Beautiful packaging effect:

The formed tray is tightly attached to the product, coupled with transparent or beautifully printed film, making the product display effect better and enhancing the attractiveness of the shelf.

The packaging shape is standardized to facilitate subsequent packing and transportation.

7. Flexibility (relative):

By changing the mold, it is possible to adapt to product packaging of different shapes and sizes.

Adjusting parameters such as vacuum degree, sealing temperature, time, gas ratio, etc. can meet the packaging requirements of different products.
