This is a good chance for you to get familiar with COLLAPSIBLE TUBES.
When it comes to collapsible tubes, plastic, laminate and aluminum are the normal materials in the cosmetic packaging industry. In this passage, we will focus on the PLASTIC COLLAPSIBLE TUBES and the LAMINATE COLLAPSIBLE TUBES.

PLASTIC COLLAPSIBLE TUBES

LDPE, MDPE, HDPE and EVOH are four basic raw materials for plastic collapsible tubes.

Firstly, the raw polyethylene (colored or none-colored) will be put into the extrusion machine, when extruding, the tubes can be in different diameter, layers or length according to the setting of the machine.
Secondly, the tubes will be in the process of automated heading machine or by manually heading machine.
Then, the next step is printing & coating, including offset printing, silk printing, hot foil, and matte or glossy varnish.
Lastly, it will come to foil sealing and cap assembling or tail sealing, and then packed for shipping.

With the advantage of barrier properties, multi-layer plastic collapsible tubes are easy to explode. The improved production now makes Plastic Collapsible Tubes a great choice for a wider range of products, such as food and pharma.

LAMINATE COLLAPSIBLE TUBES

As for laminate tubes, it can be divided into three types: ABL, PBL and HGL.
●Thanks to the properties of extraordinary Oxygen Transmission Rate (OTR) and Water Vaper Transmission Rate (WVTR), ABL tubes can better contain some oil or some saturated solution with SPF such as sun cream, also it is because the ABL tube has a layer of aluminum in the middle.
●Plastic Laminate Collapsible Tubes (PBL) have an excellent barrier and graphic printing properties. Moreover, PBL tubes retain their shape for the life of the contents. Some people may name it as APT when it doesn’t contain the EVOH.
●HGL tube is short for high gloss tube which has the best reflective effect, in other words, it illuminate.
