Courier bags how to classify?

1. Courier bag classification by material points have express plastic bags, express file seal, express bubble bags, express bone bags, express woven bags, etc.

Express plastic bags material: low-density polyethylene (LDPE) usually said PE, high-density polyethylene (HDPE) usually said PO, courier plastic bags with low cost, lightweight and other advantages.

PE and PO in the courier plastic bags difference: PE transparency, softness is better, the printing color is brighter; PO has a relatively good mechanical property; in the domestic courier bags like are using PE as the main material, while the foreign general is using PE, PO compound cooperation as the main material of courier bags.

Polyethylene courier bags in the market there are two categories: one is the new material courier bags, the second is recycled material courier bags.

Express document seal material: generally gray background whiteboard paper, white cardboard, kraft paper, mostly. The courier industry generally uses 200 g / m2 to 450 g / m2 weight of paper. Express document seal has the advantages of being flat, not easy to fold bad than the express plastic bags.

Product packing and shipping will experience a series of instability factors such as bumps, shaking, collisions, throwing, etc., which may cause product damage in the package. The application of bubbles packaging bags has reduced the rate of damage to products in transit and solved a major problem for businesses.

Here is the content list:

1. What is the role of the bubbles packaging bag?

2. What is the packaging method of a bubbles packaging bag?

3. What are the bubbles packaging bag packaging considerations?

What is the role of the bubbles packaging bag?

Most of the bubbles packaging bag is used for product wrapping, box padding, the purpose is to protect the product and packaging containers isolated from each other to avoid damage to the product in transport, handling, stacking bump, squeeze scratch; or used in the packaging container gap filling, to avoid excessive shaking of the product in transport, to ensure the safety of product transportation.

At the same time, a bubbles packaging bag can also be used as a gap filler between the product and the packaging container, so that the product is in the packaging container in a fixed state, to avoid excessive shaking collision, to protect the safety of product transportation.

What is the packaging method of a bubbles packaging bag?

1. Sharp-edged products should be cardboard, corner protection, and other things to separate the product and bubbles packaging bag to prevent scratching and loss of protective properties.

2. Use a bubbles packaging bag to fill the gap inside the box to prevent excessive shaking.

3. Use a bubbles packaging bag to wrap the product.

4. Place bubbles packaging bag around the box to do buffer protection.

What are the bubbles packaging bag packaging considerations?

1. Multi-layer packaging multi-protection.

For most goods, the use of a layer of packaging is not enough. Usually, if the goods themselves do not have the packaging, then you should use plastic bags or bubbles packaging bags as direct contact with the goods packaging materials, the outside with newspaper, fabric, or kraft paper wrapped later plus the outer packaging. If the goods themselves have a plastic bag or carton packaging, but also to add the outer packaging. So that customers receive the goods in the unpacking is still intact.

2. Leaving less space in the box.

For the use of cartons as the outer packaging of goods, need to pay attention to the filling between the goods themselves. Because in the process of delivery, if the goods are in the carton back and forth, the same is likely to break. Such gaps can be filled with newspaper dough, and small ones can use paper rolls or sponges. During the delivery process, even if the outer packaging is damaged, as long as these cushions are in place, the merchandise itself will not be damaged by breaking hard objects. In the use of bubbles packaging bag packaging process to pay attention to the above two points, to effectively prevent damage to goods.

Bubbles packaging bag is a cushioning protective packaging material, play a cushioning shock absorption role, in the packaging to be used correctly. This can reduce the impact of external impact when the product is delivered and can be a good protection of the product. Nanjing Lipack Co., Ltd produces bubbles packaging bags with excellent quality and reasonable price, which can protect the products well.

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.

Nanjing Lipack Co., Ltd. will provide comprehensive, full, and precise services for target customers is the customer to get greater value-added and create a win-win situation with customers. At the same time, we need to keep innovating, keep pace with advanced technology, and manufacture new concepts of cardboard paper boxes to serve society.
