Face Mask Packaging Machine

R320 four-side sealing stretch packing machine can pack products with PVC film. For the best packing effect, forming mold and heat sealing mold are both reasonably designed according to products’ overall dimensions.
It can also realize the vacuum packing for food, so it will make the food stay fresh for a longer time.


1.Working Principle and application

R320 four-side sealing stretch packing machine can pack products with PVC film. For the best packing effect, forming mold and heat sealing mold are both reasonably designed according to products’ overall dimensions.

It can also realize the vacuum packing for food, so it will make the food stay fresh for a longer time. 

At first, driving chain drives PVC to pass through forming mold and be formed to designed shape. Two or more workers feed materials in material feeding zone. Then the semi-finished product will be vacuum sealed by heat sealing mold. The high-precision sealing device can make sure that packages are stably and reliably sealed. Next, packages are processed in cutting station. Corners of packages will be processed. At last, end products are discharged.

If client’s products are special, a foam pad can be used to cover acute corners of product packages after material feeding. Therefore, packing sachet can be protected from damage of acute corners, packing standard upgraded and packing life also prolonged.

Application: it is suitable for the packing of mask,food, meat products, seafood, vegetable and fruit, pickles, chilled meat, medical products, hardware components and medical instruments of relatively irregular shape.

2.Control system

1)Controlled by leading PLC of Delta;

2)6-inch color HMI touch screen of Delta and pull-push control panel;

3)Servo system control of Delta for high speed and high precision;

4)Chain of TYC, cylinder and electromagnetic valve of Airtac for precise machinery coordination;

5)Low-voltage electrical appliance and perfect safety protection measures.

3.Main functions

1)The machine is of photo-electrical tracking function. Color film or glossing lamination can be used for package to reduce cost and upgrade products;

2)Combined molds enable the machine to be multifunctional and they can be changed conveniently. Besides, the molds consist of a chilling system;

3)Vacuum pump of Leybold is applied for high vacuum degree and stable and reliable quality;

4)Corner scrap winding and recycling system is more energy-saving than wasting film recycling bin, generates no noise and protects environment;

5)Leading horizontal and vertical cutting system is applied.

4.Main materials

1)Main parts of the equipment is made of high-strength 6061 aluminum and machine body of stainless steel;

2)High-quality copper alloy and high-strength engineering plastics.

5.Leading technologies

1)Lifting system is advanced from domestic simple lifting system to four-linkage lifting system with performance being more reliable. This system features stable operation, strong balance and low error rate and is ahead of other similar technologies.

2)Heat sealing and forming stations are multi-layer. Exclusive intelligent heating and distribution technology enables heating plate to heat faster and temperature to be distributed more uniformly. Due to application of leading chilling system inside the stations, the surface of stations will not be overheated like other similar machines. Therefore, burning caused by mistaken operation can be effectively avoided.

3)Film pre-tensing system is controlled by advanced automatic pre-tensing program, which can prevent packing film from being slack so that unqualified packages will not appear. Besides, automatic stretch function can save packing film effectively to reduce cost.

4)Recycling system is controlled by exclusive automatic scrap recycling function based on scrap length in order to effectively save electricity.

5)Advanced horizontal and vertical cutters is of beautiful appearance, safe performance and convenient maintenance. Products can be cut according to their own shape, which benefits reasonable technique arrangement.

6)Leading electrical control system integrates all control systems perfectly. The exclusive control and operation system thus formed greatly improves system performance.


1)Fully automatic control of industrial computer on temperature, time and vacuum pressure of forming and heating sealing;

2)Intelligent safety prevention;

3)Intelligent color film and glossing lamination distinguishing;

4)Working stations of stable lifting and micron accurate positioning;

5)Intelligent wasting corner film collection;
