Shrinking drums are often used in the chemical coatings and paints industry. As a packaging drum, what quality guarantees does it have? Let's take a look at the standards and requirements for shrinking buckets.
Since it is a packaging barrel, it must ensure that the pattern and text content of the barrel should be consistent with the pattern. There is no more printing or missing printing. The pattern and text are accurately overprinted. The inaccuracy of overprinting is not more than 0.5mm. The wall of the can and the sealing edge The tin layer should be complete, no pile tin and tin road rough, no obvious scratches and rust, no leakage caused by blisters.
The shrink-wrapped seam joint coating tape should be smooth and even, completely covering the weld seam and the blank portion, and the curing is complete without large bubbles and iron spots. Round can coating should not fall off, inflow glue, iron sulfide, no serious sulphide, oxidized ring. The shape of the round can should be complete and there should be no deformation such as cans or burrs.
There shall be no quick-mouth, false-roll and large-collapsed parts in the crimped barrel, and there shall be no incomplete curling, curled teeth, iron tongue, jump seal, curling, filler extrusion, sharp edge, and vertical Lips, double wires, etc., other defects caused by the failure of the indenter and the curling roller. The cans are required to be evenly lined, and the stencils are not pulled open or the easy-pull rings are welded.
The quality standard of the shrinking drum is that the pattern has no multi-printing and missing printing, and the seam-refilling belt should be smooth and even.https://www.fhpails.com/
