What type of packaging material does a carton belong to?

Cartons are commonly used in three layers, five layers, seven layers are used less, each layer is divided into paper, corrugated paper, core paper, face paper, lining, face paper tea board paper, kraft paper, core paper with corrugated paper, all kinds of paper color and feel are different, different manufacturers of paper (color, feel) is not the same. The following is an introduction to the various base paper materials for carton packaging:

1. Tea board paper: The color of tea board paper is grayish and white, and rough, mixed with old materials, the fiber composition is less, the quality is average, and the tea board paper is the middle layer of paper in the middle of the corrugated carton, which is very soft. Because the quality is not good, the tea board paper ** is also the cheapest.

2. Containerboard:

1) Kraft cardboard (American card, Russian card). Features: long fiber, heavy sizing, high physical strength, rough cardboard; Pure wood pulp or a small amount of OCC. Abbreviation: Imported cattle card.

2) Imitation kraft cardboard. Features: 15-25% wood pulp on the surface, the rest is OCC; The fiber is shorter and the strength is worse than that of kraft paper.

The paper surface is flat, with different degrees of sizing (water absorption ranging from 30 to 55g m2), and surface dyeing. Abbreviation: domestic cattle card.

3) White cardboard. White-faced cow card bottom, bleached wood pulp on the surface, and the rest is natural or dyed wood pulp. (Russian-Belarusian, Swedish white-card, Finnish white-card); whiteboard paper (surface bleached wood pulp, the rest is deinking or non-deinking waste paper); Coated whiteboard paper (white on white, white on gray, etc.).

4) Recycled paper. It is all composed of OCC, but it is different from corrugated paper. The surface is more than 11 AOCC noodles and dyed). The market is generally referred to as C-grade containerboard, and partly as T-paper.

3. Corrugated base paper: Corrugated paper is a multi-layer adhesive, which is composed of at least a layer of wavy core paper interlayer and a layer of cardboard. It has high mechanical strength and can withstand collisions and falls during handling.

The corrugated corrugated corrugated paper is like a connected arched door, juxtaposed with each other in a row, supporting each other, forming a triangular structure, with good mechanical strength, can also withstand a certain pressure from the plane, and is rich in elasticity, good buffering; It can be made into gaskets or containers of various shapes and sizes as needed, which is easier and faster than plastic cushioning materials; It is less affected by temperature, has good shading, does not deteriorate by light, and is generally less affected by humidity, but it is not suitable for long-term use in an environment with high humidity, which will affect its intensity.

Due to the strong protection function of contents, easy identification, easy handling, easy unpacking, exquisite printing and other characteristics of corrugated box packaging, it has become one of the fastest growing product packaging forms in recent years.

Which category does the carton packaging belong to, it seems to belong to the ester category, the schoolbag, Kappa, and then shine it out.

There are three kinds of materials for cartons, white cardboard, kraft paper version, and corrugated paper.

1. Whiteboard paper.

A kind of cardboard with a white and smooth front and a gray bottom on the back, this kind of cardboard is mainly used for single-sided color printing to make cartons for packaging, or for design and handmade products. Good whiteboard paper generally requires a tight texture, smooth surface, thick and thin oak, and no lint on the paper.

2. Kraft cardboard.

Kraft cardboard, known as containerboard paper in China, is one of the main paper types for carton paper. Domestic containerboard is divided into three grades: excellent products, first-class products and qualified products. The texture of kraft paper must be tough, with high burst resistance, ring compression strength and tear resistance.

3. Corrugated base paper.

It is one of the important components of corrugated cardboard. Corrugated base paper requires good fiber bonding strength, smooth paper surface, round to make good tightness and stiffness, and requires a certain elasticity to ensure that the made carton has shockproof and pressure resistance.

Carton raw materials:

Cartons are made of pulp raw materials, and then made of cardboard processing, printing and pressing, trimming and slotting, nailing and packaging. There are many materials that can be used to make pulp.

For example, straw stalks, wood, waste paper, wheat orange stalks, etc., these materials are pulped into paper and then pasted into cartons to complete the whole set of procedures. <>

1. Whiteboard paper: whiteboard paper is a kind of cardboard with a white and smooth front and a gray background on the back, which is mainly used for single-sided color printing and then made into cartons for packaging, or for design and handmade products. 2. Kraft cardboard:

Kraft cardboard, known as containerboard paper in China, is one of the main paper types for carton paper. 3. Corrugated base paper: corrugated base paper is one of the important components of corrugated cardboard.

1. Whiteboard paper.

Whiteboard paper is a kind of cardboard with a white and smooth front and a gray bottom on the back, which is mainly used for single-sided color printing to make cartons for packaging, or for design and handmade products. Good whiteboard paper generally requires a tight texture, smooth surface, consistent thickness, lint-free paper surface, good absorption, and small expansion rate, and can adapt to the requirements of multi-color overprinting. In order to meet the requirements of box making, whiteboard paper should also have the characteristics of large stiffness and good folding resistance.

The main import countries are: South Korea, Indonesia, the United States, Japan, etc., especially the quality of Japanese whiteboard paper is better.

Second, kraft cardboard.

Kraft cardboard, known as containerboard paper in China, is one of the main paper types for carton paper. Domestic containerboard is divided into three grades: excellent products, first-class products and qualified products. Kraft paper must have a tough texture, high burst resistance, ring compressive strength and tear resistance, in addition to high water resistance.

Due to the different processes and materials, in general, the quality of most imported kraft cardboard is better than that of domestic kraft paper, especially the quality of American kraft card. The test items are: quantitative, thickness, tightness, burst resistance, burst index, ring compression strength, transverse ring pressure index, crack length, tear degree, sizing degree, moisture, width quantitative difference, transverse folding resistance and so on.

3. Corrugated base paper.

Corrugated base paper is one of the important components of corrugated cardboard. Corrugated base paper requires good fiber bonding strength, smooth paper surface, good tightness and stiffness, and a certain elasticity to ensure that the made carton has shockproof and pressure resistance. In addition, the moisture index should be controlled, the moisture is too small, the paper is brittle, and the corrugated will crack during processing; If the moisture is too large and the paper is soft, it will bring difficulties to the processing and molding.

Generally, the moisture content of paper should be controlled at about 10. Domestic corrugated base paper is divided into four grades: A, B, C, and D.

Summary. The materials of cartons are usually as follows:1

Corrugated cardboard: Corrugated cardboard is the most important material for making cartons, which is usually composed of a layer of flat cardboard and a layer of corrugated cardboard, which has good cushioning and protection properties. 2.

Cardboard: Cardboard is a very hard material that is often used to make high-quality cartons that can withstand heavy pressure and large impacts. 3.

Wrapping paper: Wrapping paper is a thin and lightweight material that is usually used to make lightweight, low-cost cartons, suitable for some items that do not require too much protection. 4.

Kraft paper: Kraft paper is a material with high strength, which can be used to make some more important cartons, such as electronic products, hardware tools, etc. 5.

Film: Film is a material with waterproof, moisture-proof, dust-proof and other properties, and is usually used to make some cartons that need to be moisture-proof and waterproof, such as food, medicine, etc. According to different uses and needs, different carton materials can be selected to achieve the best packaging effect.

There is no big difference, just the difference in packaging.

Plastic has existed for many years, and people's lives are closely related, the emergence of plastic packaging for people's lives to provide great convenience, but the environment is very polluting. In recent years, carton packaging has gradually become popular, and simple packaging, personalized patterns and low pollution to the environment have been welcomed by people. So is it better to pack in cartons or plastic?

Let's take a look.

Carton packaging and plastic packaging occupy an indispensable position in the modern packaging industry, carton packaging is relatively expensive compared with plastic packaging, but it has the ability to pollute the environment less. In foreign countries, plastic packaging bags have basically withdrawn from supermarkets, and the packaging usually chooses the best available carton packaging, because carton packaging can generally be reused to reduce the damage to the environment.

In addition, compared with plastic packaging, carton packaging has the characteristics of easy material, light weight, easy printing, easy design and molding, etc., and is also superior to plastic packaging in protecting products, facilitating storage and transportation, and promoting sales, so it is widely used in sales packaging and transportation packaging of goods. Although the cost is higher, carton packaging is usually chosen.

The above is the introduction of the difference between carton packaging and plastic packaging, I hope it can help you.

There is no difference, it's just a matter of packaging, different packaging, different supply channels.

Hopefully mine will address your concerns.........Thank you!!

Cartons may be more environmentally friendly and less expensive.
