Cardboard

The paper bag for retail stores made of this kind of paper has a smooth surface, allowing us to print our favorite patterns or slogans on the retail paper bag. In addition, the cardboard has a certain hardness and thickness, which means that this kind of paper retail bag can withstand heavier items, such as a large box of cookies, or a heavy bottle of red wine. If you pay attention to the tobacco and alcohol counter, you will find that most wine bags choose this kind of paper retail paper bag.

Kraft Paper

Retail paper bags made of kraft paper can be said to be very common. You can see kraft paper bags for retail stores in restaurants, stationery stores, clothing stores, and so on. The retail paper bag made of this kind of paper is lighter and thinner and more convenient to carry. But also because of the thin thickness of the paper, retail kraft paper bags are relatively fragile and are not suitable for heavy or sharp-looking items, because it is easy to damage the retail kraft paper bags and cause the items in the bag to fall and be destroyed.

Art Paper

The biggest feature of this kind of retail paper bag made of art paper is its artistry. Compared with the previous two paper-based retail paper bags, which are more practical, this kind of retail paper bag will not only ensure its practicality but also its aesthetics. It has richer colors and patterns for customers to choose from and is a wise choice for wrapping gifts for relatives and friends. A retail paper bag made of art paper can make your gift more pleasing, and it also highlights the sincerity of the gift giver.

How is the strength of cardboard paper boxes designed?

1. Side compression strength = surface raw paper comprehensive ring compression strength + comprehensive corrugated paper ring compression strength * shrinkage rate general side pressure calculation according to the lowest ring compression strength of raw paper (safe and reliable), the actual test value will be appropriately greater than the theoretical calculation value.

2. Breaking strength: The maximum external force that a unit area of corrugated board can withstand before rupture is uniformly increased. Unit: Kg/cm2.

Cardboard paper box rupture strength = face paper rupture strength + middle grid paper rupture strength + bottom paper rupture strength

4. Side compression, breakage resistance, puncture with cardboard. Cardboard paper box edge compression strength will be lower than the cardboard edge compression strength (due to the loss of corrugated in the manufacturing process).

5. Cardboard paper box compressive strength = side compression strength (N/cm) * Calicut constant F. The F value depends on the perimeter length of the cardboard paper box, 2*(length + width) cm. and the corrugated flute type.

6. The compressive strength of cardboard paper box = corresponding to the compressive strength of ordinary box type * 0.6 * 1.62 * shaking cover width/carton width.

7. Cardboard paper boxes, cardboard bonding strength. As with corrugated paper boxes, the force is required to separate the unit length of cardboard face paper from the corrugated paper. Unit: N / m flute.

8. Stacking strength and compressive strength.

The required compressive strength of a cardboard paper box = [gross weight of the box * (stacking layers - 1)] * safety factor K. The former part is the static stacking strength of the cardboard paper box.

What are the design principles of the cardboard paper box?

Cardboard paper box structure design is from the actual conditions of packaging and production, based on scientific principles of the packaging shape structure and internal accessories for the design. Design must ensure that the structure has sufficient strength, hardness, and the ability to resist other environments.

Qualified cardboard paper box products start with the right structural design. Designers must not only truly understand the customer's intent, but also be familiar with the post-processing process. Designers should understand the nature, shape, size, and weight of the cardboard paper box contents, the arrangement, transportation, and stacking of the contents, the storage environment of the contents, the transportation route and time, as well as the carton box type and production materials before the design begins. Designers in determining the size of the cardboard paper box are mainly to consider two factors: one is to be able to accommodate the contents; the second is to have sufficient strength. Just like the extensions box, it's internal how can contain enough items on how to design. The constraints of the cardboard paper box size and shape of the factors in addition to the contents of the package, there are many other factors, such as ergonomic factors, the size of the pallet, the size of the truck car, the size of the container space, with the size of the shelf size. Only when the design is carried out so meticulously will it be possible to have holographic paper boxes in the future.
