The commonly used materials and techniques of cosmetic packaging materials
ABS belongs to engineering plastic, which is not environmentally friendly and has a high hardness, so it cannot be directly in contact with cosmetics and food. In acrylic cosmetic packaging materials, ABS is generally the material of inner cover and shoulder cover. The color is yellow or creamy white.
PP and PE belong to environmental protection materials, which can be directly in contact with cosmetics and food. They are the main materials for filling organic skin care products. The natural color is white and translucent. Depending on the molecular structure, three different degrees of hardness and softness can be achieved.
PET is an environmentally friendly material, which can be directly in contact with cosmetics and food. It is the main material for filling organic skin care products. The PET material is soft and its natural color is transparent.
PCTA and PETG are environmentally friendly materials, which can be directly contacted with cosmetics and food. They are the main materials for filling organic skin care products. The materials are soft and transparent, and PCTA and PETG are soft and easy to scratch. And do not often spray painting and printing.
AS is not high hardness, more crisp (when it hits the crisp sound), transparent color, and the base color blue can be directly contact with cosmetics, food, in the ordinary emulsion bottles, vacuum bottles are generally the material of the bottle body, can also make small capacity cream bottles. It is transparent.
The material is hard, transparent and the background color is white. And acrylic in order to maintain the transparent texture often into the outside of the bottle spray, or in the injection molding for coloring.
In order to better understand the packaging material technology of cosmetics, we carry out process analysis and explanation on all kinds of commonly used packaging materials of cosmetics, so that we can quickly understand the packaging material product knowledge. First of all, let's analyze the common knowledge of cosmetic packaging:
1. Vacuum bottle product technology
It is composed of cover, shoulder sleeve, vacuum pump and piston. Use by air pressure. The sprinkler that place matches has chicken beak tip head (have all plastic also have is outside a layer of anodized aluminium), duck beak flat head was outside bread a layer of plastic.
2. Lotion bottle
It is composed of cover, shoulder sleeve, emulsion pump and piston. Most are equipped with internal hoses. It is exterior acrylic more, inside PP material pledges. The cover is ABS in acrylic outside.
3. Perfume bottle
1. Internal components are made of glass and external aluminum (rotating and non-rotating according to the cap).
2. PP bottle (full PP for small injection)
3. Glass drip irrigation
4, the inner bladder of perfume bottle is glass type and PP. Large capacity to use glass, because the storage time is longer, PP is suitable for small capacity short-term storage. Most PCTA and PETG don't carry perfume.
4. Cream jar
There is an outer lid, an inner lid, an outer bottle and an inner bladder.
1. External acrylic and internal PP material. The cover is coated with PP gasket inside ABS in acrylic
2. Internal ceramics, PP external anodized aluminum, cover external anodized aluminum, PP internal ABS plus a layer of PP gasket.
3. Full PP bottle with a layer of PP gasket inside.
4. External ABS internal PP. There is a layer of PP gasket.
5. Blow molding bottle
The material is mostly PET. There are three kinds of lid, clamshell and screwing. Blow molding is the direct blowing of the bottle embryo. Characterized by a bump on the bottom of the bottle. It's brighter in the light.
7. Aluminum plastic tube
The inner one is PE material and the outer one is aluminum packaging. And offset printing. Cut out and then rewind. According to the pipe head divided into round pipe, flat pipe, oval pipe. Price: round tube < elliptic tube < flat tube
8. Plastic tube
All PE material, and pull out the hose before cutting offset printing, screen printing, hot stamping. According to the pipe head divided into round pipe, flat pipe, oval pipe. Price: round tube < elliptic tube < flat tube
