High Speed LDPE Zipper Bag Production Line

This equipment is specifically designed for producing films with zipper structures, enabling simultaneous film extrusion and zipper profile forming. Through key technologies such as screw extrusion, air ring cooling, and film belt tension control, it ensures a smooth film surface and a secure zipper seal. Its high-speed production capacity makes it an ideal machine for manufacturing zippered self-sealing bags.

This model employs a combined water-cooling and air-cooling system, focusing on improving the transparency and dimensional stability of zipper film. It is suitable for the production of high-quality zipper bag films, and performs exceptionally well in food packaging and applications with stringent film material requirements.

This model is primarily designed for the integration of blown film production and zipper structure for LDPE material films. The equipment is equipped with synchronous feeding, a touch interface, and an automatic alarm control system, enabling efficient coordinated production of zipper film and bag material, suitable for manufacturing various sizes of zipper bags.

Flexographic printing presses use flexible resin plates for printing and are characterized by their simple structure, easy operation, and high printing speed. They can perform multi-color continuous printing on various materials such as plastic film, paper, and non-woven fabrics, producing clear and vibrant images. Widely used in food packaging bags, diaper bags, shopping bags, labels, and other fields, they are a commonly used and highly efficient piece of equipment in the packaging and printing industry.

Gravure printing machines use high-precision engraved metal cylinders as the printing medium, enabling high-definition printing of richly detailed patterns. The equipment is highly stable and suitable for long-term, high-speed operation, widely used in food packaging films, composite films, pharmaceutical packaging, and daily chemical product bags. The printed effect is smooth and glossy, suitable for customers with high image quality requirements.

This model is equipped with automatic roll changing, electronic shaft synchronization control, and a constant tension system, enabling high-speed continuous printing. It is suitable for mass production of multi-layer composite films and colored packaging bags. The equipment is energy-efficient, highly accurate in registration, and can be used in conjunction with bag-making and laminating equipment, making it an ideal choice for high-end packaging and printing plants.

Used to cut wide films or composite films into rolls of the required width, equipped with an automatic tension and correction system, resulting in smooth cuts and precise positioning.

The bag surface is smoother and more transparent. It is especially suitable for producing high-quality zipper bags, such as fruit bags and cosmetic bags, and can handle packaging with high appearance requirements.
