Specialty paper

1. There is a wide variety of specialty papers; commonly used in packaging materials include embossed paper, patterned paper, and gold- and silver-foil paper, among others.

2. These papers undergo special treatment to enhance the texture and premium feel of the packaging.

3. Embossed paper and patterned paper cannot be printed; gold foil and similar materials, however, can be printed using four-color process.

Composite bag

1. Composite bags are suitable for vacuum packaging or general packaging of products such as food, tea, electronics, chemicals, and pharmaceuticals.

2. The available processing methods are essentially the same as those for paper, including silk screening, printing, and hot stamping.

Blistering

1. Blister packaging is made from a transparent material, with PVC, PE, or PET as the primary raw materials.

2. Can be used directly in place of paper to make boxes, or can be formed together with paper cards.

3. Can be silk-screened, printed, or hot-stamped.

4. Offset printing is feasible, but the print quality is relatively high; for small-run production, screen printing is typically used.

OPP bag

1. OPP bags are made of stretchable polypropylene, which is a type of plastic—essentially, they are plastic bags.

2. Before placing the product in the outer box, first slip it into an OPP bag to ensure it looks clean and hygienic.

3. It features high transparency and relative brittleness, and can also be printed with various patterns and perforated as required.

Heat-shrink bag

1. This is a type of bag that exhibits significant shrinkage upon reaching a certain temperature, used for protective packaging.

2. It is used solely for packaging protection and no other processes are performed.
