Read： 679 Time：15months ago Source：Transform the World with Simplicity

BOPP (biaxially oriented polypropylene) is a common chemical raw material, widely used in packaging, printing, electronics and other fields. Due to its special physical and chemical properties, BOPP needs to comply with certain safety regulations during storage and transportation to ensure the safety of personnel and the environment. This article will detail the safe storage and transportation specification of BOPP.

1. the physical and chemical properties of BOPP

BOPP is a colorless, transparent film material with high tensile strength, tear strength and impact strength, as well as excellent chemical resistance and insulation. However, BOPP also has some special physical and chemical properties, such as flammability, easy to generate static electricity, etc., so it needs special attention during storage and transportation.

2. the safety storage specifications of BOPP

1. Storage environment requirements: BOPP should be stored in a dry, ventilated and cool environment, avoiding direct sunlight and high temperature. At the same time, the storage environment should be kept clean and avoid contact with corrosive substances such as acid and alkali.
2. Storage and stacking requirements: BOPP should be neatly stacked to avoid excessive extrusion and friction, so as not to cause damage to the film surface or static electricity accumulation. At the same time, the stacking height should be reasonably designed according to the warehouse conditions and the weight of the film to ensure the stability of the stacking.
3. Fire safety measures: Because BOPP is flammable, the storage warehouse should be equipped with corresponding fire fighting equipment and facilities, such as fire extinguishers, fire hydrants, etc., and regular fire inspection and maintenance.

3. BOPP safety transport specification

1. Packaging requirements: BOPP should be packaged with suitable packaging materials during transportation, such as cartons, wooden frames, etc., to ensure that the film will not be damaged during transportation.
2. Requirements for transport vehicles: BOPP transport vehicles should have fire prevention, anti-static and other functions, and keep clean and dry, to avoid contact with acid and alkali and other corrosive substances.
3. Safety measures during transportation: During transportation, severe vibration, friction and extrusion should be avoided to avoid damage to BOPP or static electricity accumulation. At the same time, the transportation process should maintain a smooth driving, avoid sudden braking or sharp turns and other operations, so as to avoid unnecessary losses to the goods.

4. of electrostatic protection measures for BOPP

Because BOPP is easy to generate static electricity, it is necessary to take electrostatic protection measures during storage and transportation to avoid safety accidents such as fire or explosion caused by static electricity. The following are some common electrostatic protection measures:

1. Control environmental humidity: Appropriately increasing the humidity of the storage and transportation environment can effectively reduce the generation and accumulation of static electricity.
2. Use anti-static materials: During storage and transportation, anti-static materials can be used for packaging or bedding to reduce the generation and transmission of static electricity.
3. Electrostatic grounding: electrostatic grounding of storage and transportation equipment can lead static electricity into the ground to avoid the accumulation of static electricity to a dangerous level.

In short, BOPP, as a common raw material for chemical production, needs to comply with certain safety regulations during storage and transportation to ensure the safety of personnel and the environment. By understanding the physical and chemical properties of BOPP, taking appropriate storage and transportation methods, and taking effective electrostatic protection measures, the risk of safety accidents can be greatly reduced, and the safety and stability of production can be guaranteed.
