What Are Some Common Cushioning Packages?
Common cushioning packaging materials mainly include foamed plastics (EPS, EPE, EPU), pulp moulding and paper wood chips. Foamed plastics have good cushioning properties, so they are widely used in cushioning packaging and play a pivotal role, but their shortcomings are also very prominent:
(1). The volume is large, specific storage space is required, and the transportation cost is high;
(2). For different products, special moulds are required, which requires a long development period and is expensive;
(3). Difficult to recycle and easy to produce pollution, especially EPS;
(4). The appearance in general, and the EPS is easy to break or produce debris under local stress. Although pulp moulding and paper sawdust have sound environmental protection effects, they have a poor cushioning effect. Coupled with their rough, easy-to-generate dust and other characteristics, they cannot meet the cushioning packaging requirements of fragile or precision industrial products.


Why Choose Packaging Air Bags?

In response to the problems mentioned above, Packaging air bags as a new type of cushioning packaging material entered the field of vision of merchants and consumers. Compared with traditional cushioning materials, packaging air bags material not only has an excellent cushioning effect but also occupies a small area before being filled with air and has lower storage and transportation costs;
Packaging air bags are mainly in several available sizes and specifications, which can be selected according to different product needs, so no special moulds are required, the development cycle is short, and the cost is low; Packaging air bags are not only transparent but also clean and easy to print so that they can improve the product image. Bringing a good shopping experience to consumers and recyclable is conducive to environmental protection. Packaging air bags, a cushioning packaging material, will become a packaging material that conforms to the needs of the times and has excellent development prospects.

Advantages of Packaging Air Bags:

(1). Environmental protection: waste reduction, less dust working conditions;
(2). Low cost: reduced packaging volume, reduced transportation costs, reduced workforce and warehouses.


Applications of Packaging Air Bags

These advantages of Packaging air bags are favoured by merchants, making packaging air bags have a wide range of applications. In terms of products, it can be used in household appliances, electronic products, food, ceramic and glass fragile products, instrumentation industries, etc.; in terms of function, it can be used as a close-fitting wrap package for products, corner protection of products, and filling of remaining space.

With the improvement of packaging reliability requirements and the expansion of product types and applications, various merchants have specially made different packaging air bags for their products. More applications are suitable for desktop refrigerators, computers, washing machines, large electronic appliances, etc. Packaging includes end-type packaging suitable for portable computers, hard drives, electronic devices, etc., letter-like packaging suitable for pharmacy products, mail orders, single-piece assembly items, etc., and protective packaging suitable for large items, home appliances, furniture, etc. Corner packaging and bottle packaging, ideal for alcoholic beverages, decorative bottles, etc., are also called inflatable bag packaging.

The application of packaging air bags in the market has become more extensive, and its excellent cushioning performance can play a perfect role in protecting the products in transportation. There are different names for this air cushion in the market, composed of 99% air and 1% plastic film. Most of them are air column bags, air cushion bags, packaging air bags, bubble bags, etc. An Air column bag is a bag-like product made of multiple continuous air column monomers through a specific design and heat-sealed to hold items. After inflation, it can better wrap the product. It is mainly used for protective product packaging and can reduce transportation. The acceleration of the shock in the medium achieves protecting the product. Based on the independent air chamber structure principle, when one air column is damaged, other air chambers are not affected, so the entire buffer protection effect is not affected.


Packaging Air Bags Product Features

Packaging air bags is a structural design based on air cushions. After a specific heat seal design, it is a complete cushioning packaging form used for special product packaging to protect the product in an all-around way. The cushioning of Packaging air bags mainly relies on the compressed air filled in the air bag and the surface film. In application, due to its composition, the shape, volume and weight of the products that can be packaged in the air bag are restricted. When inflating the air bag, different air chamber widths and different inflation amounts will significantly impact the air bag. The air chamber with a large width can hold more gas, and the thickness after inflation is also more significant, and different inflation amounts will directly determine the air pressure in the air chamber so that the air bag exhibits different load-bearing and cushioning characteristics. Therefore, the characteristics of the air bag material, the width of the air chamber, the pressure of the air chamber, and the structure of the air bag will be several indispensable factors for studying the characteristics of the inflatable bag.


The Main Structure of Packaging Air Bags

Packaging air bags are mainly composed of an air column, one-way valve, inflation port and inflation channel. After being inflated, a hollow bag-shaped container is formed, and the desired product is placed in it, and the product can be wrapped around it, which has a good protective effect. The constituent unit of the inflatable bag is still a single air cushion, so the composition of the air cushion is a key part of the inflatable bag.

Components of Packaging Air Bags
1. Film
There are two common materials for airbag film materials. One is a PA/PE film made of extremely high-strength PA (Oriented Polyamide) combined with linear low-density polyethylene (LLD-Polythene). The other is a PE/PE film co-extruded by low-density polyethylene (LD-Polythene).

The thickness of the film used in Packaging air bags is usually between 60um and 120um. At present, the thickness of 70-80um is more common in the market. The applicable ambient temperature of Packaging air bags is between -20℃~60℃, but the time should not be too long in a high and low-temperature environment, and it is better not to exceed 12h.

2. Air chamber
The air cushion film is divided into independent spaces by heat sealing, which is called air chambers. Different air chamber sizes are accompanied by different inflation amounts and size differences after inflation, which brings different bearing and cushioning properties to the air cushion.
Impact. Common air cushion air chamber sizes are 2cm/3cm/4cm/6cm/8cm/10cm/12cm, etc. However, when making packaging air bags, due to the moulding requirements and size constraints of packaging air bags, the one that is usually used is The width of the air chamber is 2cm/3cm/4cm. Generally, different air chamber widths are suitable for different product weights. On the market, manufacturers use 2cm/3cm for packaging products below 20kg and 4cm for packaging products below 100kg.

3. Check valve
The one-way valve is also called the check valve. Due to the function of the check valve, the compressed air will not overflow after entering the air chamber through the check valve, which can keep the performance of packaging air bags stable. The check valve is formed by heat-sealing two high-strength thermoplastic films, one of which is coated with high-temperature resistant ink so that no heat effect is generated during heat sealing, and an opening is formed to facilitate the entry of gas and use the gas in the airbag at the same time The pressure closely adheres the two films, thus sealing the opening, preventing the gas from flowing back, and realizing the airbag sealing.

Production and Application of Packaging Air Bags

Packaging air bags are formed by a number of continuous air column monomers through a certain amount of heat sealing—the common air bag form on the current market. In the inflatable bag packaging process, the required packaging is usually put in first, and then the air filling.


Packaging Air Bags Market Application Status

Packaging air bags are favoured by large and small businesses due to their excellent protection and low cost. Existing packaging air bags are widely used in express logistics transportation packaging, and the product types are becoming more and more diversified, mainly bottled Red wine, bottled drinks, canned milk powder, cosmetics, hard drives, etc. The common features of these products are regular and sleek appearance, small size and lightweight. Packaging air bags cover all aspects of it, which can well protect the product from damage or serious deformation caused by external impact. And its lightweight, transparent and visible, not only reduces the weight of the entire express but also brings a clean and beautiful shopping experience to consumers and increases consumer satisfaction.
