Description

Technical Field

[0001] The utility model relates to the technical field of plastic barrels, in particular to a plastic-lined barrel. Background Art

[0002] Plastic barrels are mostly used for the storage and transportation of various liquids. They have good properties for special packaging of hazardous goods. They are not easy to break, rust-proof, light in weight, and have excellent oil and strong corrosion resistance. They are mostly used for packaging hazardous goods that require heat preservation, moisture resistance, pressure resistance, and corrosion resistance. However, after long-term use, a large amount of stains remain on the inner wall of the barrel, which is not conducive to later cleaning. Moreover, the inner wall cannot be cleaned at any time during use, which increases the difficulty of cleaning and causes waste. For this reason, we propose a lined plastic barrel to solve the problems raised in the above background technology. Utility Model Content
