Moderate cost: The plate making cost is low, but the labor cost is high.

Application scenarios: Handbags, canvas bags, custom gift bags, etc.

4. Digital printing

Digital printing is a direct printing technology that does not require plate making, and has gradually become popular in recent years due to its flexibility and efficiency.

characteristic:

High flexibility: suitable for small batches, personalized customization, and can quickly change patterns.

Good printing effect: high color reproduction, suitable for complex patterns and gradient colors.

High cost: The cost of single printing is higher than traditional printing, making it suitable for short version orders.

Good environmental friendliness: using eco-friendly ink to reduce waste.

Application scenarios: high-end gift bags, promotional bags, personalized customized bags, etc.

5. Heat transfer printing

Thermal transfer printing is a technique of transferring patterns from a transfer film to a substrate through heating.

characteristic:

Excellent printing effect: clear patterns, bright colors, suitable for complex designs.

Limited applicable materials: mainly used for plastic films and textiles.

High cost: The cost of transfer film and equipment is relatively high.

Medium production efficiency: suitable for small and medium-sized batch production.

Application scenarios: plastic bags, non-woven bags, clothing bags, etc.

6. Offset printing

Offset printing is a traditional printing technique mainly used for paper bag making products.

characteristic:

High printing quality: suitable for fine patterns and high-quality printing.

Limited applicable materials: mainly used for paper and cardboard.

Moderate cost: The plate making cost is relatively low, suitable for medium batch production.

Generally environmentally friendly: The use of ink may contain harmful substances.

Application scenarios: paper bags, handbags, gift bags, etc.

7. Combination printing

Combination printing is the combination of multiple printing techniques to meet complex design and high-quality requirements.

characteristic:

Excellent printing effect: Combining the advantages of multiple technologies to achieve high precision and high color expression.

High cost: requires multiple equipment and processes, suitable for high-end products.

High flexibility: The printing method can be adjusted according to the needs.

Application scenarios: high-end packaging bags, luxury bags, special customized bags, etc.

8. UV printing

UV printing is a printing technology that uses ultraviolet curing ink and has been favored in recent years due to its environmental friendliness and high efficiency.

characteristic:

High printing quality: clear patterns, bright colors, suitable for fine printing.

Good environmental friendliness: using UV ink, no harmful substances evaporate.

High cost: Equipment and ink costs are relatively high.

Wide applicability: can be used for various materials such as plastic, paper, metal, etc.

Application scenarios: high-end plastic bags, cosmetic packaging bags, food packaging bags, etc.

9. Cold hot stamping

Cold hot stamping is a technique of transferring metal foil onto a substrate using glue, commonly used to enhance the high-end feel of products.

characteristic:

Excellent visual effect: Strong metallic luster, enhancing product grade.

High cost: Metal foil and process costs are relatively high.

Wide applicability: can be used for materials such as plastic and paper.

Application scenarios: luxury bags, high-end gift bags, holiday promotion bags, etc.

10. Laser printing

Laser printing is a technique that uses laser technology to directly engrave patterns on a substrate.

characteristic:

Unique printing effect: The pattern has a three-dimensional and glossy feel.

Good environmental friendliness: No need for ink, reducing pollution.

High cost: The equipment and technology costs are relatively high.

Limited applicability: mainly used for plastic and metal materials.

Application scenarios: high-end plastic bags, anti-counterfeiting packaging bags, etc.

There are various printing technologies for bag making products, each with its unique advantages and applicable scenarios. Choosing the appropriate printing technology requires consideration of factors such as material characteristics, production batch size, cost budget, and printing effect.
