The styles of handmade paper boxes include top and bottom covers, sugar plate covers, drawer-type, swing cover, round box, special-shaped box, etc.; the styles of machine-made paper boxes include drawer-type, plug-in type, plug-in bottom cover, four swing covers, adhesive bottom cover, etc.

   According to the shape, it can be divided into six types: envelope type, square bottom type, swing belt type, M-shaped folding type, cylinder type, and valve type.
   Paper can (tube):
   It is a cylindrical container made of paperboard as the main material, and is equipped with a paper cover or a bottom cover made of other materials.
   It is used to replace tinplate cans for the sales packaging of powdery, granular objects, cakes, dried fruits, etc.; after the inner wall of the paper can is coated with waterproof material, it can also be used as a packaging for liquid oil.
   Paper cups:
   Generally, they are small paper containers for cold drinks, with large mouths and small bottoms. They can be stacked one by one for easy access, storage and transportation.
2. Main features
   Can effectively protect products: Packaging containers made of cardboard have certain strength and elasticity, while cartons made of corrugated cardboard have significantly better elasticity than packaging containers made of other packaging materials.
   Suitable for various production methods: Paper containers can be made by hand or by mechanized large-scale production, and the production efficiency is very high.
   Many structural changes: Paper containers can be designed in various forms, such as round, square, etc.; they can also be lined with boxes, extended with swing lids, pressed curves, and opened with windows.
   Easier to process: Paper and cardboard have excellent foldability and are easy to fold into the desired shape.
   Excellent printing performance: Paper and cardboard are made of interwoven fibers, easy to absorb ink and paint, and the printed patterns and text are clear and firm.
   Small space occupation: Many paper containers can be folded into flat plates for easy transportation and storage.
   Low cost: Paper packaging materials have abundant raw materials and are easy to produce, so paper containers are relatively cheap.

   Hygienic and non-toxic: Paper packaging materials are harmless to the human body, especially for food packaging.
3. Main disadvantages
   Low compressive strength: limits the stacking height of goods.
   Easy to absorb moisture: the box becomes soft and deformed. To prevent paper containers from getting damp, moisture-proof agents can be applied on their surfaces or plastic materials and paperboard can be used to compound the box.
