In the cosmetics industry, the quality of packaging is the product of second life.
According to the characteristics of the cosmetics and other factors, such as sales, choose the right plastic hose as packaging, can make the cosmetics under high quality packaging foil more show charm.
a safety, health,
cosmetics direct contact with the human body, it puts forward the health security of the high requirements on the packaging. Should from the raw material for plastic hose safety ( Raw material particles must conform to the relevant laws and regulations, such as the FDA, SGS certificate, etc. ) , production process, production control, so as to ensure the health of built-in cosmetics safety.
2, protective
cosmetics packaging materials should be enough mechanical strength, a certain degree of barrier property, chemical resistance, weather resistance, etc. , to prevent the cosmetics produced in the process of filling, storage and transportation quality problems.
1, the mechanical properties. The most main function of packaging is to use its mechanical properties to ensure the content is not damaged. Cosmetics wrapping plastic hose, the mechanical properties such as compressive resistance, impact resistance, resistance to bending strength and so on, mainly according to the nature of packaging products, packaging machinery, storage and transportation demands, etc. In general, plastic hose must have certain stiffness, to ensure the overall shape of the product in good condition; At the same time also need to have good resilience, to ensure that the extrusion can return to its original shape. However, in the same material composition and the thickness of the same conditions, the stiffness and resilience is a pair of contradictions, only has carried on the balance between the two, to meet customer demand.
2, blocking performance. Cosmetics packaging plastic soft commonly used block material with aluminum foil, EVOH, oxide coating PET and nylon, etc. , the barrier property because of the differences between the material and thickness of the different. Aluminum foil with high barrier property, for example, when the thickness of aluminum foil in more than 25 microns, the blocking performance of up to 100%; EVOH on oxygen barrier property and its thickness is proportional to the, 15 microns thick EVOH oxygen transmission rate is about 0. 3 to 0. 4cc/m2·24h（ Mocon test) ； Oxide coating the PET oxygen transmission rate generally is 0. 2 to 1. 0cc/m2·24h（ Mocon test) 。 Therefore, we should according to the requirements of the packaging of cosmetics to choose barrier property of different materials. In addition, the interactions of fragrance and packaging materials should also be considered, such as polyolefin material absorption of essential oil, can be in at this time between the aluminum foil and polyolefin materials increase a layer of protective coating.
3, chemical resistance and weatherability. Cosmetics wrapping plastic hose, the choice of materials should have the contents of chemical corrosion resistant performance, including the oil resistance, grease resistance, acid resistance, etc. , can according to actual conditions and needs, matrix resin for optimization to meet the application requirements, such as HDPE LDPE have better chemical resistance.
the material of plastic hose weather resistance and temperature resistance, dimensional stability, environmental stress cracking resistance and so on factors, only with the short or long term performance of plastic hose, in order to ensure safety and quality of cosmetics. Some cosmetics is suitable for use in cold winter, for example, if the use of conventional material such as PP plastic hose, the possible drop test do not pass, tube and a series of problems, this is because the glass transition temperature of PP in - Around 10 ℃, low temperature brittle, fragile. Where you need to adjust the formula structure of plastic hose, toughening materials use, improve the impact strength of plastic hose.
3, operational
in order to facilitate the printing and packaging operation, to adapt to the mechanized operation, cosmetics packaging plastic hose should have good printing eligibility, heat sealing performance and packaging machine eligibility, etc.
1, printing eligibility. From the Angle of printing, lu: su composite hose and all plastic is plastic extrusion hose has more advantages. Because aluminous model and all plastic composite hoses are to different material made by squeezing the complex process sheet, after cutting, printing process after the pipe, after or in the printed film again after extrusion compound, cutting process pipe; The plastic extrusion hose is pipe before printing, will inevitably lead to the complexity of the printing process.
2, heat sealing performance. Heat sealing performance include the sealing temperature and heat sealing strength of two indicators. Demand of cosmetics, especially some win min tail pipe welding sealing temperature not too high, the thermal cover can use some of the low temperature heat sealing materials, to ensure the quality of cosmetics is not affected under the condition of low temperature welding sealing. When filling the cosmetics, the content may contaminate the sealing, adopt the general material processing plastic hose to the good sealing, but if hot cover with anti pollution materials, can effectively solve the problem. Four, economy
in the aluminum-plastic composite tube, aluminum foil unit price highest, control the thickness of aluminum foil can effectively control the cost of the hose. So, on the premise of can ensure excellent product performance, use a thin aluminum foil, reduce the loss in the process of production, as far as possible using simplified packaging, can reduce the cost of aluminum-plastic composite tube.
the current high cost of all plastic composite hoses, without affecting the performance under the premise of thinning thickness is also one of its future development direction. As a result, high stiffness materials ( Such as PP, etc. ) Will be more and more applied to all plastic composite hoses.
to reduce plastic extrusion hose printing costs, and to take advantage of its appearance ( Endless seal) , a new kind of tube structure has been formed. This structure is on the outside of the printed composite hoses through a special process set on a transparent plastic extrusion hose together, make the printing design is clearly appear in front of consumers, while maintaining the good feel of plastic extrusion hose total.
