The company’s most significant advantage is that the company has today’s advanced gravure high-speed printing machine, flexographic printing eight-color machine, four-color machine, blow molding machine and a complete set of post-process equipment. Provide customized packaging bag services to meet each customer’s individual needs, including size, color, material, etc.

get quote

Customers must provide source files in formats such as AI.PSD.CDR for design and layout. If there is no design draft, they can communicate with our packaging bag manufacturer to offer design ideas, and the information must be carefully checked.
Take food packaging bags as an example: after the specification, material, thickness, and bag type of food packaging bags are determined, enterprise designers or professional design and production teams should make design drawings based on these data. In the design process, reference suggestions should be given, and the bag type should be finally determined.
Particular attention should be paid to the information on the packaging bag, such as manufacturer’s name, ingredients, product introduction, place of origin, net weight, specifications, food label number, QS certification, hygiene license number, production date, storage conditions, shelf life, edible method, manufacturer Name, address, product barcode, and contact number, etc.
After all the details are determined, our professional quotation staff will quote the customer.

plate making

After the artwork is determined, professional technicians are required to color-separate the pattern and repair some dark places; simultaneously; it takes more than a dozen processes to complete the plate making.
Generally, composite plastic flexible packaging is a gravure printing process, requiring engraving a copper plate first. The copper plate is engraved according to the pattern and size of the customer’s plastic packaging bag, so once the copper plate is engraved, it is dedicated to the particular bag and cannot be modified. Neither the size nor the surface of the bag can be changed. The price of a set of copper plates is relatively high, so before making plates, customers must be cautious to confirm that the pattern and size will not be wrong.


After the raw materials are ready, the surface film is printed with a high-speed printer. During the printing process, there is a plate cylinder for each color; the engraving of the plate cylinder is concave. We offer digital, plate, and cylinder printing.

compound bag

The printed surface film and the easily heat-sealable inner film are compounded with a particular high-speed peritoneal machine for special glue;
a plastic packaging bag is made by compounding several layers of movies of different materials, and the compounding process is to combine these. The layers are firmly compounded together. The compounding process should generally be checked first if a plastic packaging bag has a layering phenomenon during use.


After compounding, it needs to be cured in a curing room above 45 degrees for more than 24 hours in order to make the food packaging bag not easy to delaminate.

bag making

At this time, the production of food packaging bags has come to an end. The bag-making technicians need to have specific skills. They must ensure that the edges of the color-printed packaging bags are well-sealed and air-tight and have specific technical skills in the temperature control of the hot knife. After inspection by the quality inspector, it leaves the factory; the slitted and reminded roll film is placed on the bag-making machine for bag making. Such as the zipper bag-making machine, which can manufacture self-supporting bags with zippers, eight-side sealing bags, etc.

Check quality

The main items of packaging bag inspection include specifications (length, width, thickness), appearance, overprint error, color difference, peel strength, heat sealing strength, etc.
Length and width are measured with a ruler, and thickness is measured with a thickness gauge.
The color difference is mainly checked with the standard seal sample, and the color difference at the arm distance should be consistent. In terms of color, Jianhongxing Packaging will also use a 50x magnifying glass to check the printed matter’s color carefully. Generally, paints are made up of dots one after the other. If the color is wrong, the bubbles will appear irregularly distributed.
Overprint errors are mainly checked for double-sided printing by visual inspection.
The AGS-5KG electronic universal testing machine mainly tests peel and heat seal strength. The detection principle is the same as that of the computer tensiometer.
