Although there are many varieties and functions of cosmetics, their appearance and packaging adaptability from cosmetic packaging manufacturer are mostly liquid, emulsion or paste, which do not have a distinctive appearance. They must be beautifully unique with cosmetic packaging design to show their characteristics. Therefore, cosmetics generally rely on cosmetic packaging, so that sales can be well realized, except for metals. Plastic and glass are the main cosmetic packaging materials, such as plastic cosmetic tubes, plastic and glass cosmetic bottles. There are different opinions about who will lead the trend of the cosmetic packaging market in the future.
1. Glass cosmetic bottle and jar as cosmetic packaging material
As a traditional cosmetic packaging material, glass has the following characteristics: bright and transparent, good chemical stability, airtight, easy to form, but heavy, easy to break. 80% - 90% of glass cosmetic packaging containers are glass bottles and cans. The density of a soda-lime glass bottle is usually 2.5-2.6g/cm3, which has high brittleness and low thermal conductivity. Using metal ion colourant can make emerald green, dark green, light cyan, amber and other colours of glass.
1.1 advantages of cosmetic glass packaging containers from cosmetic packaging supplier

1.2 disadvantages and use restrictions of glass cosmetic packaging containers revealed by cosmetic packaging manufacturers:
① It is brittle and easy to break
② Heavyweight and high transportation cost
③ The energy consumption is high and the environmental pollution is serious
④ Poor printing performance
Restrictions on the use of cosmetic glass bottles:
Although the glass cosmetic bottle has good chemical stability, it is not easy to react with the contents, and has high transparency, iron, cobalt and chromium colourants can be added to the raw materials to produce glass bottles of various colours; It has a good heat resistance and is not easy to deform, high compressive strength, internal pressure resistance, high density, sense of weight (suitable for the packaging of higher grade cosmetics), good barrier, sanitation and preservation, easy to seal, and can be resealed after opening, etc. but at the same time, the glass cosmetic bottle has poor impact resistance, fragile, high filling cost, and complex moulding process, which limits the application of glass bottle.
Cosmetic glass bottles are often used in the packaging of high-grade cosmetics or cosmetics with special requirements.
In the past, cosmetics were usually packaged in glass makeup bottles, but due to the single variety of glass cosmetic containers, even if there is a better design idea, it can not be realized due to the limitations of technology and materials.

③ Good processing performance, such cosmetic containers from plastic cosmetic packaging manufacturers can be made into a variety of specifications and sizes of bottles, caps, films, bags and composite packaging materials.
④ Good decorative colouring and printing performance. Drug labels, instructions, labels and barcodes can be directly inkjet or printed on plastic materials without falling off.
⑤ Good chemical stability, weak toxicity, health and safety.
2.2 disadvantages and limitations of plastic packaging containers
① Easy to carry static electricity
② The surface is easily polluted
③ Discards can cause environmental pollution
④ Recycling is difficult
Limitation of use: for ordinary cosmetics, plastic containers or composite containers are often used to pack plastic or composite materials. Plastic containers and composite containers are often used for packaging. However, glass bottles are usually used for packaging high-grade cosmetics or volatile and easily flavoured cosmetics, such as perfumes.
3. Plastic cosmetic tube and plastic cosmetic bottles will be the main trend of cosmetic packaging in the future
The cosmetic packaging market has always been dominated by glass, but the diversity and plasticity of plastics make plastics become increasingly popular packaging materials, and the market demand will increase greatly《 World cosmetic packaging 2000-2005 pointed out that for multinational cosmetic companies, the cosmetic packaging is an integral part of product design, and plastic tube packaging for cosmetics is gaining popularity.
In addition, in recent years, the global cosmetic market has grown at an average annual rate of 15%, with annual sales reaching nearly 50 billion yuan. By 2005, the number of packaging products will increase to 73 billion yuan, of which plastic products will account for 61%. It is predicted that the annual sales will reach 80 billion yuan by 2010. Relevant data also show that in recent years, plastic cosmetics packaging has occupied more than 80% of the packaging market share of cosmetics, and has become the most important packaging containers for cosmetics
The packaging of middle and low-grade cosmetics is mostly replaced by plastic bottles, bags or tubes. Glass cosmeticbottles account for less than 8% of cosmetic packaging containers. According to the international market research company, the reason why plastics are widely used is that for a series of bath products, plastics have advantages over glass, and the versatility of plastic products can support the increasing diversity of end-user products.
3.1 there are many kinds of plastic cosmetic bottles and plastic cosmetic tubes with different functions
Cosmetic plastic bottles and tubes are small in specific gravity, easy to colour and strong in plasticity. They can be made into various bottle shapes at a low price and are suitable for large-scale production. To increase the decorative effect of plastic bottles and cosmetic tubes, in addition to bottle printing, colouring materials can also be added during production to make bottles of various colours, To meet the needs of different grades of packaging, metal vapour dyeing, gold plating and hot printing can also be used for surface decoration.
When plastic bottles & cosmetic tubes are used to package all kinds of cosmetics, the makeup bottle shape, colour, transparency and various decorations are changed a lot which is to highlight the characteristics of products and promote sales. For example, when transparent cosmetic glass bottles are used for packaging, only simple line printing is generally carried out to highlight the clear and transparent characteristics of products and attract consumers. When wholelsale plastic bottles and makeup tubes of various colours are used for packaging, the bottle body is usually printed or pasted with labels for decoration. To convey the message of the product. Win the favour of consumers. To arouse the curiosity of consumers and stimulate their desire to buy, we should design the new bottle shape and cap, and cooperate with the design of the bottle body to show the characteristics of the product. Sometimes, colour printing carton, windowed carton and plastic bottle are used to form sales package.
Plastic materials and their composites are widely used in cosmetic packaging by plastic cosmetic tube and bottle manufacturers. The design of packaging makeup containers, especially plastic cosmetic bottles, tends to be diversified. Plastic packaging containers are mostly obtained by film plastic method, and their shape is mainly determined by the moulding method and the mould used, which is convenient for manufacturing various special-shaped bottles. There are many kinds of plastic cosmetic packaging containers with different functions. The material of plastic container determines their basic characteristics.
The plastic bottles commonly used to package cosmetics mainly include polyethene bottles (blow moulding), polyvinyl chloride bottles (injection moulding, stretch blow moulding), polyester bottles (stretch blow moulding), polystyrene bottles (injection blow moulding), polypropylene bottles (extrusion blow moulding), etc. With the continuous development of new technology and new products, plastic cosmetic containers have achieved the transparent characteristics that only glass had before, making plastic products unique in the cosmetics packaging market.
