Why is the kraft paper widely used in the packaging industry?

Lishimei thinks this is really a so good question. As the good facts, the kraft paper can be widely use.

Kraft paper packaging productions have the advantages of low production cost, easy production and processing, high bursting strength, good printing effect, light weight, logistics and transportation, foldable to reduce storage space, non-toxic and tasteless, degradable and pollution-free, and is widely favored and praised in the market.

Advantages of kraft paper:

1. Environmentally friendly. In fact, kraft paper is a kind of recyclable packaging material. At present, the environmental protection problem is increasingly serious, and the world's understanding of environmental protection is also more profound. The concept of "plastic with paper tape" has a long history. Kraft paper, as an environmentally friendly recycled product, is exactly its value, and will continue to develop in the near future. It is an important feature of kraft paper packaging.

2. Low cost; The overall cost of kraft paper packaging is relatively low, which is in line with the requirements of merchants to control costs, and also in line with the long-term development trend of the market.

3. Simple style. A simple and elegant kraft paper packaging method with retro characteristics is also favored by the majority of consumers. Many well-known brands have adopted this kraft paper packaging method, and have taken a fancy to its retro characteristics.

4. Security. Some kraft paper has a food-grade certificate and can directly contact with food, so it has great advantages in food packaging, such as paper cups, paper bowls, lunch boxes, etc., such as McDonald's, Starbucks, etc.

5. Physical properties. Kraft paper is highly breathable, non-toxic, odorless, pollution-free, high-strength, wear-resistant, etc. This also makes kraft paper widely used and can be selected by all walks of life.

Certainly, Lishimei think these disadvantages of kraft paper should be noted when use them to make the packaging productions:

1. Poor water resistance; The physical properties of wet kraft paper will be greatly reduced, and the unstable strength is the important reason. Therefore, kraft paper is not suitable in some environments.

2. Printing effect. Compared with the white card, the printing effect of kraft paper is also relatively poor, because its surface is relatively rough, especially when it shows bright colors, it seems a little inadequate. Therefore, kraft paper is generally not used for packaging that requires high printing effect.

3. Color difference. Kraft paper with color difference will also have color difference in different batches and different production times. Therefore, the color stability is slightly poor.

How to choose the right kraft paper to produce the packaging productions?

Lishimei usually make such choose:

If it is the warp paper, the kraft paper can choose the weight from 60sm to 150gsm.

From the 150gsm to 250gsm krat paper, it can be used in the corrugated carton, paper bags and paper card.

From the 250gsm to 450gsm kraft paper, the kraft paper can be used to make the paper boxes, paper card, envelopes, mailer bags and others.

Lishimei hope these can help you.
