1. First of all, consumers need to guide the raw materials of transparent plastic products including polystyrene and organic glass. The raw materials for translucent plastic products include cellulose plastics, low density polyethylene, epoxy resins and unsaturated resins.
2. For the raw materials selected in the plastic bucket, the new materials are the best;
3. See if the plastic bucket has a relevant production license, such as a dangerous goods packaging product license issued by the state;
4. Look at the various performance indicators of the product. Such as mechanical strength, heat resistance, and solvent resistance.
In addition to the factors that must be considered in the above four points, there are many essential factors that can help us identify the quality of the stacking barrels, such as price. Many companies now consider the price first when choosing plastic buckets, and the second is quality. This seems very reasonable, because profit and cost are there, and everyone is willing to lower the cost, the better, and the higher the profit, the better. Many powerful companies will have their own proprietary departments to analyze the possible profit and loss risks of the products, including cost and profit.
Plastic barrels are mostly used for the storage and transportation of various liquids. They have good characteristics for special dangerous goods packaging. They are not brittle, non-rusty, lightweight, and have good oil and strong corrosion resistance. Packing of dangerous goods with thermal insulation, moisture resistance, pressure resistance and corrosion resistance. Plastic barrels are mostly made of polyethylene, polypropylene, polyester and other plastics by blow molding, injection molding, blistering, and rotomolding. They are mostly used to hold liquid and solid items in the chemical, pesticide, pharmaceutical, food, hardware, electronics, and mechanical and electrical industries. . Specification from 0.25L--220L
Open and close plastic buckets and 1000L container plastic buckets. Can be used to store items or transport turnover. At present, the maximum capacity of plastic barrels produced by the rotomolding process can reach 50 tons.
Some products can be used for hot filling, and the general temperature should not exceed 60 ℃. After hot filling, the lid should be closed and stacked after the contents have cooled down sufficiently to room temperature. The weather resistance is above 60 ℃ --40 ℃.
As a kind of container, plastic barrels can be used for storage and transportation, etc., which are well received by everyone. What are the advantages and disadvantages of popularizing plastic buckets for you next?
Plastic barrels can store and transport liquid and solid chemical products, food, medicines and dangerous goods; plastic barrels have the same weight as fiber barrels, but are half lighter than steel barrels; plastic barrels do not sag, generally do not corrode, and can be more than steel barrels. Use 1 to 5 times; can be moisture-proof, waterproof, and non-corrosive; can be recycled and processed without waste pollution; its material has good weather resistance, the use temperature is 20 ~ 60 ℃; this bucket is different from flexible plastic bucket, it has the ability to withstand Ability to palletize loads.
However, plastic buckets have the key problem of permeability. It is difficult to clean them after use. Food is never allowed to be repackaged when recycling reuse buckets. Plastic buckets are prone to stress cracking and strict requirements on materials and processing. Electrostatic charges can diffuse into the cargo, so flammable liquid cargo cannot be canned; the compatibility mechanism between plastic drums and cargo is complicated, especially the impact on food may have potential hazards and is difficult to find.
