What Are The Types Of Crown Caps That Can Be Generally Divided Into According To The Form?

Crown caps are generally divided into single-piece caps and double-piece caps according to the form; Single piece cap: there is no gasket inside the cap, the whole cap material is the same, relying on folding edges or inner plug sealing; Double piece cap: there is a gasket inside the cap, the gasket material is soft, relying on the rebound force of the compression gasket to maintain the seal; Comparison: (1) The single-piece cap is not padded and does not need a padding machine, so the investment in crown cap equipment is less than that of two-piece cap. And the price of gasket material is more than twice that of cover body material, and the cost of single-piece cover is lower than that of double-piece cover; (2) The single-piece cap has high requirements for the size and shape of the bottle mouth; The folded edge monolithic cover is sealed by the rebound force of the folded edge deformation to press the outer edge and end face of the bottle mouth; The inner plug monolithic cap is sealed by the interference fit between the outer diameter of the inner plug and the inner diameter of the bottle mouth. The gasket of the double-piece cap is softer and has a greater tolerance for defects in the bottle finish.

What is the production of crown caps?
1. The crown cap is made of high-quality aluminum, which is hygienic, will not rust, easy to open, no auxiliary tools, after opening, the crown cap is destructive and can effectively prevent theft.
2. Crown bottle cap has the advantages of good cushioning, earthquake resistance, heat insulation, moisture resistance, chemical corrosion resistance, etc., and is non-toxic, non-absorbent, dust-free peeling and scaling, increased, and the sealing performance is very good.
3. Crown bottle caps can be made into stainless steel pellets according to customer requirements high temperature resistance, boiling resistance, alcohol resistance, etc., and the pattern design can adopt color printing, embossed characters, milling words.
4. The inner cushion of the crown bottle cap adopts special glue dropping material and advanced production technology, so that it has excellent airtightness after sealing the bottle, and the surface of the crown cap cap has a larger plane, which makes the printing of various text logo patterns, crown bottle cap more beautiful, and also makes your products more valuable.
