As the name suggests, packaging cartons are used to wrap items. It is one of the common cartons in our lives and one of the indispensable items in logistics. It is not only environmentally friendly and recyclable, but also bears important responsibilities for packaging, maintaining goods, and being beautiful. The physical performance index of the packaging carton becomes the basis for its quality evaluation. The packaging carton helps us protect the goods. Do you know its advantages and what tests it needs to pass before it can leave the factory?
Because packaging cartons are often used to transport and protect products, they also have strict requirements on their own quality.
Packaging cartons testing items include: compression resistance, side pressure, adhesive strength, puncture, simulated transportation shock resistance, drop, etc. Display of testing instruments.
The equipment corresponding to the compression test generally has an auxiliary structure to form a space that can be adjusted at an even speed on the upper and lower sides. During the test, place the carton between the two sides, press down on the upper pressing surface of the instrument at an even speed, and test the maximum force when the carton is crushed.
The edge compressive strength tester tests the vertical compressive strength of the carton board after sampling, which is generally expressed as pressure/length.
Drop test machine: It simulates the deformation of the carton when it is dropped from a high place during transportation or handling. Test methods include: face drop, edge drop, and corner drop.
Advantages of packaging cartons:
✦ Carton packaging is convenient for mechanized production and packing and sealing assembly line operation, high production efficiency, easy to realize packaging standardization.
✦ Light weight, easy to load and unload, can avoid or reduce being dropped during loading and unloading, thus reducing the damage rate.
✦ The use and distribution costs of carton packaging are low. The price of a three-layer corrugated carton with the same inner diameter is only 1/3 of that of a wooden carton, and it can save about 20% of shipping costs; Save more than 10% on shipping costs.
✦ Clean and firm, can be tightly sealed, when the box is covered with plastic lining, it has good dustproof and moistureproof performance, so it can effectively protect the safety of goods.
✦ Packaging cartons are easy to fold and lay flat, save storage space when stacked, easy to carry, and easier to handle or recycle than wooden boxes after use.
✦ It is easy to leave traces of stolen goods in the box, so it can effectively prevent theft of goods, and the insurance company will accept it when insuring water damage insurance and theft and pick-up are not dangerous during sea transportation.
