It has been decades that makeup plastic cosmetic tube companies acquire the system of manufacturing the tube sleeve. Related to other sleeve elements such as PBL, ABL, and aluminum, the PE tube is more comfortable to take and more excellent elastic flexibility. Moreover, cosmetic plastic tube is more eco-friendly to our atmosphere which is 100% recyclable. Many packaging companies can generate monolayer cosmetic tube and Co-Ex multilayers plastic tube packaging with EVOH.
Cosmetic Tube Printing Process
When the decoration department receives the tube sleeve, you will activate the printing process. The engineer feeds the tube sleeve into an offset print device. The initial move is to corona outflow on the tube cover. By executing a high volt load on the tube surface, it generates infinite holes for printing inks to pack. All cosmetic packaging tube companies follow these processes.
Secondly, the printing base will be cleaned by UV printing ink, and then the printing plate shifts the ink onto those innumerable holes of the tube frame. Later printing the tube body, the tube with ink moves to a UV light dryer to solidify the UV ink. Once the ink is solidified, the hour engineer coats the varnish around the tube body. The varnish can be glossy, matt, or semi-matt depends on the consumers.
Screen Printing & Foil Hot Stamping
Most consumers want some more detail after offset printing and coating varnish; they will pick silk screen printing and foil hot stamping on the cosmetic tube exterior. The generation of screen printing is identical to offset printing. But, the ink of screen printing is more solid than offset printing. Consumers could feel the ink thickness on the tube cover.
Foil thermal stamping is an excellent method to show your brand logos! According to the study, the first area that the consumers see is a brand logo. The goods are more beautiful than those without warm foil stamping by placing a hot foil stamping of the brand's logo. After offset printing, varnish coating, and cover printing on the tube sleeve, the engineer shifts the foil via a stamping plate heated by over 200 Celsius. The cosmetic packaging tube industries have to meet all these conditions.
The initial stage of the production process is extrusion. A blend of resin and color concentrate is put into an extruder hopper. The extruder is temperature-controlled as the resin is filled through to assure a clear melt of the resin.
The material is extruded into a set of sizing dies encapsulated within a right-angle cross-section connected to the extruder. At this point, the cover is water-cooled and available for cutting. The cover is filled through a collection of dies, at which time it is sliced to a provided length by just revolving the knife. You can achieve the stability of the production process in one of three methods.
The most popular way for cosmetic packaging tubes in the U.S. is the "downs" method of compression, forming the head onto the cosmetic tube. In this method, the cover is put on a conveyor that carries it to the heading section where the shoulder of the head is attached to the body of the tube while, at the same time, the thread is created.
The sleeve is then put on a mandrel and carried down to the slug pick-up location. The hot melt tape or slug is fixed onto the sleeve's end and then carried onto the mold station. At this point, in one section, the edge of the shoulder, the thread, and the orifice are formed at the end of the sleeve. The head is then cooled, separated from the mold, and carried into a clip conveyor.
Two other heading techniques are utilized in the U.S. and are seen widely common. Injection molding of the head to the sleeve and an extra concentration molding process whereby a heated donut of resin material is released into the mold station rather than the hot-melt strip or slug.
The beaded cosmetic tube is then moved to the accumulator. The accumulator is devised to support the heading and decorating progress. From here, the tube continues to the decorating operation, where, with offset printing, flexographic, silkscreen, and cold foil, it is polished. The tube is carried from the pin chain to a print mandrel. As the tube joins the printer, the first stage is a surface treatment; either corona, plasma, or flame treatments prepare the tube's surface to accept ink.
For offset printing, each color is carried onto a central plate by a set of rollers. The plate then gets connected with a rubber blanket, pulling up the ink and carrying it onto the tube's circumference. The wet ink on the tube is preserved by ultra-violet light or heat. For graphics, silkscreen, and cold foil, the inks are applied to the tube surface individually, and an ultra violet-like cures the ink after each color or contrast.
After painting, a conveyor carries the cosmetic tube to the capping location, where the cap is joined and torqued to the customer's terms. In some industries, the cap is implemented first, then decorated so that the adjustment of the front of flip-top closures is arranged with the front of the tube's artwork. The cosmetic tube container is then transported to a conveyor belt and carried into a tray in either circumstance. The trays are arranged into cartons that are sealed and available for shipment.
Considered the perfect packaging resolution for the cosmetic tube industry and its great aesthetic purpose and easy adjustability to many decorative patterns, the seamless plastic tube market is an interesting horizon for the packaging business. The tube manufacturers have fortunately been producing and distributing plastic tubes to new and developing areas through continuous variation. Many leading manufacturers of plastic tubes worldwide have supported us consume comprehensive and cutting-edge knowledge and expertise in the sector. Seamless plastic tubes are utilized for packaging high-end, low-volume goods in a variety of industries. They give improved shelf life for products and assist in producing a unique product identification.
