As a common material for cosmetic packaging, plastic bottles are commonly made of PP, PE, PETG, PET, acrylic, ABS, AS, MS, PS, etc., and are combined into a variety of bottle types according to different material characteristics to be inspected by quality inspectors. Although the acceptance of packaging materials is generally done by cosmetic OEMs, as a brand owner knows the test specifics and is clear about the problems that arise with the package materials, it can better communicate with cosmetic OEMs.
Here is the list of contents
The main points of cosmetic plastic bottle testing
Essentials of common materials for cosmetic plastic bottles
Whether the package is hygienic and whether there are defects in appearance, which can be checked with the naked eye, things like airtightness, capacity, number of pump starts, printing adhesion, leaks, drips, etc. all need to be tested and test reports issued.
In addition, there are also requirements for packaging at the national regulatory level. For example, China's General Administration of Market Regulation has revised and released the national mandatory standard "Restriction of excessive packaging requirements for goods Food and cosmetics", excessive packaging will be subject to more severe penalties. Chanel, Gucci, Guerlain, and Dior have all been notified and even punished for excessive packaging.
Excessive packaging refers to the packaging void rate, the number of layers of packaging, packaging costs exceed the standard, the general requirements of the outer packaging shall not exceed 3 layers, 50ML cosmetics packaging void rate shall not exceed 30%, packaging costs do not exceed 20% of the product sales price, the specific can use the network tool to calculate the cosmetic packaging void rate.
l cosmetic plastic bottles are usually made of PP, PE, K material, AS, ABS, acrylic, PET, etc.
l Usually used for cosmetics class containers with thicker walls cream bottles, caps, stoppers, gaskets, pump heads, dust covers for injection molding; PET blowing bottles for two-step molding, tube embryos for injection molding, finished packaging for blowing bottles. Others such as lotion bottles with thin container walls and washing bottles are blowing bottles.
l PET material is an environmentally friendly material with high barrier, lightweight, unbreakable characteristics, chemical resistance, extremely transparent, can be made into pearlescent, colored, magnetic white, transparent, widely used in containing gel water. Bottle mouth is generally standard 16 #, 18 #, 22 #, 24 # caliber, can be used with the pump head.
l Acrylic material for injection molding bottles, chemical resistance is poor, generally can not be directly filled with cream, need to match the liner barrier, the filling is not easy too full to prevent the cream into the liner and acrylic bottle between, so as to avoid cracking, transportation in the packaging requirements are high, because the scratch looks particularly obvious, high permeability, the sense of the wall is particularly thick, but the price is quite expensive.
l AS transparency is better than ABS, and better toughness.
