Introduce The Aluminum Film Woven Fabric As A Shipping Packaging Material

Sea transportation is one of the common methods in international trade, and the packaging and transportation safety of goods are equally crucial. In this process, the quality and applicability of shipping packaging materials are extremely important. Vacuum aluminum film woven fabric packaging material is one of the commonly used high-performance packaging materials in sea transportation. This article will provide a detailed introduction to the application scope and specific process flow of vacuum aluminum film woven fabric, with a focus on how to correctly apply and extract vacuum.

1, Application scope of vacuum aluminum film woven fabric

Aluminum film woven fabric is a high-strength material composed of plastic film and aluminum foil layer, and is made using traditional weaving techniques. Due to its unique structure and excellent performance, it is suitable for various packaging and sea transportation scenarios.

1. Frozen food

Due to the high temperature and humidity requirements of food, the packaging materials of frozen food must be able to withstand the high temperature and humidity during sea transportation. The high strength and moisture resistance of vacuum aluminum film woven fabric can help maintain stable temperature and humidity inside the packaging, thereby ensuring food safety and quality.

2. Electronic products

In the field of electronic products, vacuum aluminum film woven fabric is an ideal choice for protecting electronic products and components. Due to the presence of sensitive circuit boards and components in electronic products, which are affected by adverse environments such as vibration, friction, and static electricity, it is necessary to choose packaging materials that can provide good physical and electrical isolation capabilities.

3. Medical equipment

Medical equipment needs to be carefully packaged and transported to ensure that its functionality and technical performance are not affected. Therefore, packaging materials need to have properties such as moisture resistance, shock resistance, anti-static, and sound insulation. The aluminum foil layer of vacuum aluminum film woven fabric can effectively shield radiation and magnetic fields, preventing medical equipment from external interference.

2, Packaging process flow of vacuum aluminum film woven fabric

The packaging process of aluminum film woven fabric involves several key links. The following is the specific process flow.

1. Preparation work

Before operating the vacuum aluminum film woven fabric, we need to ensure that the working environment is clean and free of dust and dirt. At the same time, the workplace must have corresponding equipment, such as vacuum pumps and heaters.

2. Packaging

Put the items that need to be packaged into a vacuum aluminum film woven cloth bag to minimize the air in the packaging bag as much as possible. Fold the opening of the packaging bag and seal it with a sealing tape.

3. Vacuum pumping

Put the sealed packaging bag into the vacuum box, connect the vacuum pump to the vacuum box, and turn on the vacuum pump to remove the air from the vacuum aluminum film woven cloth bag. When there are effects such as bending of the packaging bag wall, and it does not affect the vacuum effect, the pump can be stopped in an appropriate amount. After the bag swells up, flip the bag and continue to vacuum, so that all the oxygen in the bag is extracted.

4. Sealing

After the vacuum effect is achieved, quickly turn off the vacuum pump, match the seal pattern with the aluminum foil bag, and stick a 6-10mm pressure-sensitive sealing tape. Enterprises should use inspected and qualified sealing machines for installation and sealing operations, and the seals should be neatly cut with no air leakage.

3, Precautions for vacuum pumping

The correct vacuum packaging process is crucial for ensuring the transportation safety of goods. The following are the precautions to be taken during the vacuum extraction process:

1. Operators should wear appropriate protective equipment, such as gloves, protective masks, etc.

Before using a vacuum pump, it is necessary to ensure that the pump is running well and that the suction and exhaust ports are not blocked.

3. When the items in the vacuum packaging bag have a high moisture content or other liquid substances, they need to be dried before being placed in the vacuum bag, otherwise it is easy to damage the vacuum pump. In addition, for better moisture-proof effect, the air in the packaging bag must be extracted clean.

4. During the vacuum pumping process, it is necessary to pay attention to controlling the pumping speed and intensity. Once there is deformation of packaging items, the pumping speed should be immediately slowed down.

5. The aluminum foil layer in the packaging bag should be kept at a certain distance from the heating plate to prevent the aluminum foil from melting.

In summary, aluminum film woven fabric is a high-strength and multifunctional material for vacuum packaging, with a wide range of applications, including frozen food, electronic products, and medical equipment. During the use of vacuum packaging, it is necessary to strictly follow the correct process flow and operating methods to ensure that the performance of vacuum aluminum film woven fabric is fully utilized.
