storage environment

Temperature: The storage temperature should not exceed 38 degrees Celsius in summer, and attention should be paid to moisture prevention. In winter, the temperature should not be lower than 10 degrees Celsius to prevent freezing and hardening.

Humidity: It is recommended that the packaging and packaging workshop maintain a constant temperature and humidity between 20-25 ° C and 55-70 RH.

 If it cannot be achieved, it is recommended to use air conditioning to control the heat temperature in summer and water heating and humidification control in winter.

Light exposure: It should be placed in a cool, dry, and ventilated environment, avoiding direct sunlight.

packaging method

Inner packaging: Using film bags or composite bags, it must meet performance requirements such as moisture resistance and pressure resistance.

Outer packaging: corrugated cardboard boxes are used, and special packaging is specified in the supply contract.

Storage precautions

Do not store it alone in the air to prevent moisture absorption and drying.

During each use, the hands holding the water-soluble bag must be dry to avoid contact with any liquid to maintain the integrity and strength of the bag.

 Open the outer packaging bag, take out the required water-soluble bag, and seal the outer packaging bag until the next use.

The product must be placed in a dry, room temperature, or warm environment.

It should be waterproof, moisture-proof, anti pollution, anti damage, strictly prohibited from scratching, anti squeezing, and strictly prohibited from dropping goods from high places.

PVA is a type of adhesive material. After being produced in water-soluble bags and transported by logistics companies, it may cause the goods to be squeezed. Picking up the water-soluble bag will show that it is not open. In this state, simply pick up a stack of water-soluble bags from the bottom and hit them onto hard objects (such as wooden boards or iron tables) to open them.
