  Exterior visual effect inspection includes the flatness and clarity of the vacuum bag inspection and other new items. The key is to test whether the surface layer has significant scratches and needle holes, sealing has zero pollution, etc.

  The actual way of appearance inspection is as follows:

  1: vacuum bag surface metal wire drawing "inspection. Put the vacuum bag in the hand, pointing to 40w fluorescent light gently shaking, according to the composite bag surface refraction light, can clearly find the vacuum bag surface is not scratch or mark, the industry is often called "bag surface metal wire drawing". Most of the metal wire drawing conditions are caused by the plastic bag making machine pulling the correct guide roller is not clean, so it is necessary to ensure that the guide roller is clean. In addition, the guide roller does not rotate will make the vacuum bag caused by metal wire drawing common faults.

  2: Check the flatness of vacuum bag. The vacuum bag is placed alone on the leveling table. If the surface layer is bent, warped outward or arched inward, it indicates poor flatness, and on the contrary, it indicates excellent flatness. The reason for the poor flatness generally has the following aspects: the temperature of the production bag is higher, has destroyed the in-situ stress tensile strength of the composite bag layer; Unscientific structure; The thickness of raw materials is not uniform.

  3: Check the clarity of vacuum bag. For some products, clarity seems to be crucial because of the large scale of unpatterned designs. The INSPECTION MEANS OF CLARITY IS: EXTRACT BAG OF A PIECE OF FINISHED PRODUCTS, THROUGH THE INDIRECT LAMP SOURCE INSIDE THE ROOM TO VIEW CHECK, IF BLANK HAS "BLACK DOT", "RING THING", "FOG" AND OTHER CONDITIONS, SHOW CLARITY IS POOR, EXPLAIN CLARITY IS GOOD ON THE CONTRARY.
