What are the composite materials used for bag making products in Dalian?

The demand for bag making products in Dalian is widespread, and with the development of e-commerce and logistics industries, the demand for bag making products will continue to grow. At the same time, the promotion of environmental policies and the improvement of consumer environmental awareness will drive the transformation of bag making products towards environmental protection and sustainable development. In the future, bag making products will pay more attention to environmental performance, functionality, and aesthetics to meet the needs of different fields.

Bag making products can effectively protect the contents from external physical damage, moisture, dust, light, and other factors, extending the shelf life and service life of the products. Putting products into bags facilitates sorting, stacking, and transportation, improves logistics efficiency, and is also beneficial for product storage and preservation.

What are the composite materials used for bag making products in Dalian?

Composite of plastic film and paper

Features: Combining the moisture-proof, waterproof, and barrier properties of plastic film with the printing performance, texture, and environmental friendliness of paper. Paper provides a good printing surface for exquisite graphic and textual printing, while plastic film enhances the durability and moisture resistance of the bag.

Application: Commonly used in packaging bags for industries such as food and daily necessities, such as cookie bags, laundry detergent bags, etc.

Composite of plastic film and aluminum foil

Features: Aluminum foil has excellent barrier properties, which can effectively block light, oxygen, and moisture. When combined with plastic film, it can greatly improve the freshness, fragrance, and light avoidance performance of packaging bags. Meanwhile, plastic film provides excellent flexibility and heat sealing performance for composite materials.

Application: It is widely used in food, medicine, cosmetics and other fields with high requirements for packaging barrier performance, such as sealed bags in milk powder cans, drug blister packaging, cosmetics essence packaging bags, etc.

Multi layer plastic film composite

Characteristics: According to different usage requirements, various plastic films with different properties are composite together, such as composite films with good tensile strength and high barrier properties, or composite films with good heat resistance and good flexibility, to obtain composite materials with excellent comprehensive performance. This composite material can meet the packaging needs of different products in terms of strength, barrier properties, heat resistance, cold resistance, and other aspects.

Application: It is widely used in industries such as food, chemical, and electronics. For example, high-temperature steaming bags are used to package convenience foods and can be sterilized at high temperatures; Electronic component packaging bags are required to have good anti-static and moisture-proof properties.

Composite of paper and fiber materials

Features: Adding fiber materials such as glass fiber, carbon fiber, plant fiber, etc. to paper can improve its strength, toughness, and wear resistance. At the same time, fiber materials can also endow composite materials with some special properties, such as glass fiber can increase the rigidity of the material, carbon fiber can improve the conductivity of the material, and so on.

Application: Commonly used to make bags that require high strength and durability, such as industrial packaging bags, building material packaging bags, etc. In some special fields, such as electronic device packaging, composite bags containing carbon fiber can be used to prevent static electricity from damaging electronic components.

Composite of plastic film and non-woven fabric

Features: Non woven fabric has the characteristics of softness, breathability, and high strength. When combined with plastic film, it can improve the feel and breathability of plastic film while maintaining some of its advantages, such as waterproofing and moisture resistance. This composite material also has good tear resistance and durability.

Application: Commonly used for making shopping bags, clothing packaging bags, agricultural cover bags, etc. In today's increasingly environmentally conscious world, shopping bags made of composite plastic film and non-woven fabric have received widespread attention and application due to their reusable, high strength, and relatively environmentally friendly characteristics.

Common types include three sided sealed bags, four sided sealed bags, self-supporting bags, zipper bags, organ bags, tote bags, etc. Three sided and four sided sealed bags are relatively basic bag types that are easy to make; Self standing bags can stand on shelves for easy display and use; Zipper bags have the function of being repeatedly opened, making it easy to access and store items; The organ bag can be unfolded or contracted as needed, increasing the capacity of the bag; Handbags are convenient for carrying items.

Bag making machine: It is the core equipment for bag making, with multiple models and functions according to different bag making processes and bag types. Common bag making machines include three side sealing bag making machines, four side sealing bag making machines, self-supporting bag making machines, etc. Printing machine: used for printing on packaging materials. Depending on the printing process, there are gravure printing machines, flexographic printing machines, digital printing machines, etc.
