The prefammers made of PS materials such as their toughness are as a disposable product.The bottle mouth and the bottle have no contraction, no flat bottle, no side wall deformed, no protrusion, no depression. Everyone should know what the role of the bottle embryo is, and its production materials are more commonly used plastic materials, there are other related.
PP material This material can be said that it is good in the bottle material, completely reaches the food grade requirements, but there is also a disadvantage, which is not good plastic, so the cost of processing is relatively high. The role of the bottle embryo: the intermediates can be better viewed later, if there is an unexpected address, it can be simply approached, and it is not a waste after the completion of it.
Semi-finished products and then processed into end products. Materials for bottle billets: Materials for bottle billets include PVC materials, PET materials, PS 32 400 FLIP TOP CAP Suppliers materials, and PP materials.The bottom of the bottle is good, no depression, no convex, no central point deviation, no breakage of the bottom, no layers, mouth unable to exceed the bottom plane.
Inspection method of the bottle quality: the end face of the bottle should be flat, no damage gap, the thread is complete, no disintegration, no overflow wireless, the inside and outside should not have oil. Later, naturally, it can be better invested to the preparation of the criteria, and save some mistakes, thereby better protecting the benefits of our photo. I believe that everyone has an answer.
