Inline Atomosphere Modified Vacuum Packing Machine Tray Sealer

The continuously modified atmosphere packaging machine is a box-type modified atmosphere fresh-keeping packaging machine launched by the company for cold fresh meat, cooked food, etc. The food is isolated from the outside air, and the tray is filled (2-3 kinds of gases are mixed according to the characteristics of the food) to keep the packaged food in its original flavor and appearance for a long time, and to inhibit various bacteria and microorganisms to the greatest extent. breeding. Thereby extending the shelf life or shelf life of the food.

Inline Atmosphere Modified Vacuum Packing Machine Tray Sealer


The product is suitable for fast and efficient modified atmosphere fresh-keeping packaging of chilled fresh meat, cooked meat products, fast food, cakes, rice noodles, cheese, soy products, aquatic products, poultry meat, etc. It has the characteristics of keeping food quality, freshness, color, shape, and taste.

The working process of the machine – put the packaging box with the packaged objects on the feeding conveyor belt. When the machine is running, the box feeding mechanism will send the packaging box to the mold, and the film feeding mechanism will send the film to the top of the packaging box and pack it in the mold The air in the box is drawn out and filled with fresh-keeping gas, and then heat-sealed (the film is sealed with the packaging box), fried and cut. The packed box is sent to the discharge conveyor by the box feeding mechanism. At this point, a wrapping cycle ends. It greatly improves production efficiency, reduces labor and costs, and avoids the impact of human factors.

Machine Details


Atomosphere Modified Vacuum Packing Machine Tray SealerVideo

Machine Feature:

1 Alloy frame.

Completely abandoning the iron channel steel frame structure, this machine adopts a cold-drawn aluminum-magnesium alloy frame body and stainless steel channel steel connection support surface covered with 304 stainless steel door, corrosion resistance, good straightness, high structural strength, not easy to deform. It ensures the transmission accuracy of the packaging film and other characteristics and is suitable for use in various environments.

2 Japan IDEC PLC intelligent control system

This machine adopts a Japanese IDEC PLC programmable controller and Taiwan Weilun human-machine interface touch screen control system to set various parameters intuitively and accurately, run stably and reliably, operate more concisely and conveniently, and is more user-friendly.

3 German vacuum pump

Using Germany 100 vacuum pump, high vacuum, stable performance, low noise, extremely low failure rate, durable and long life (vacuum pump brand and model can be selected)

4 Advanced film coating device

Using Japanese Panasonic sensor control, the sensor tracking automatically corrects the precise alignment of the packaging film and the packaging box, ensuring beautiful packaging and smooth and stable operation of the film. Equipped with an air pump, it is more convenient to put the membrane up and down and reduce labor.

5 Roll film rubber roller

The film feeding and receiving are conveyed by rubber rollers, the film runs smoothly, and the adjustment is convenient and durable. When loading film, adjust the handle to provide convenience for film loading

6 Replaceable Die System

The food is packaged by means of fully enclosed vacuum replacement, that is, in the state of the fully enclosed vacuum chamber, the vacuum pump is used to evacuate, so that a high degree of vacuum is formed in the vacuum chamber. For skin packaging, replaceable sealing molds are used, and users can change the shape and specifications of the trays used at any time according to their needs. One machine with multiple functions to meet the needs of different products

7 Waste film collection system

The independent waste film collection system is adopted and the air expansion shaft is installed, which is easy to understand and easy to disassemble. As long as the gas is released, the waste film can be replaced to maintain environmental hygiene.

8 304 stainless steel body and curved design

The material of the equipment body is made of 1.5MM 304 stainless steel, which has the characteristics of corrosion resistance, rust resistance and durability. To ensure stable and long-lasting operation of the machine in various working environments. The surface of the casing adopts a curved design, which is especially suitable for the operator’s waistline comfort and security. We have humanized design for every detail.

9 Finished product output, conveyor

The conveyor transports the packaged finished products out for sub-packaging, and different conveyors can be customized according to user needs.

10 Box feeding mechanism

Put the box containing the packaged material on the feeding conveyor belt, and the box feeding mechanism is controlled by the motor to accurately send the packaging box into the mold for packaging, ensuring that the box feeding is accurate. The automatic box feeding function greatly improves production efficiency, and saves time, labor, efficiency, etc. The width of the box guardrail can be adjusted according to the size of the box.

11 Multi-purpose machine
