Collapsible tubes are cylindrical packages that can be used to dispense viscous liquids like toothpaste or creams. They are typically made of aluminum, plastic, or other metals. Aluminum tubes are produced through impact extrusion and can be printed on. They are suitable for perishable items. Plastic tubes are commonly made of polyethylene and are popular for cosmetics and some foods. They retain their shape after squeezing unlike other materials. Tin, zinc, and lead were also historically used to make early collapsible tubes.

2. COLLAPSIBLE TUBE
• It is a collapsible package which can be used
for viscous liquids such as toothpaste, artist’s
paint, oinments, and so on.
• Basically tube is a cylindrical, hollow piece
with a round or oval profile.
• Most tubes are designed to be dispensed with
hand pressure, but some are used with a tube
key at the base to help roll them up.

4. ALUMINIUM
• Aluminium tube caps and closures are
generally threaded, as is the nozzle.
• The tube is hermatically sealed and nearly
grem-free due to the high temperatures
during the production process.
• Aluminium tubes are produced by impact
extrusion from a small round blank.

5. • Designs can be printed on to the tube using
wet-in-wet offset printing method.
• The filled content can be squeezed out by
finger pressure.
• Aluminium tubes are especially suitable for
the packaging of highly perishable contents.
• APPLICATIONS: Used for cosmetics,
pharmaceuticals, food paint and technical
products

7. PLASTIC
• Tubes can also be produced in plastic, most
commonly polyethylene.
• Plastic tubes are popular for cosmetics such
as hand creams, and also some foodstuffs.
• The plastic tube retains its shape after each
squeeze unlike laminate tubes such as
toothpaste tubes.

8. • Plastic tubes can be highly decorated or have a
special additive such as soft touch to make the
tube more appealing during use or at the point
of sale.
• Plastic tubes are produced by extrusion.
• Tube printing using specialized printing
machines such as silk screen printing applies
the desired decoration.
• Multi- layer plastic tubes have become
increasingly popular; they isolate the contents
better from the air, allowing them to be used
for a wider range of products, such as food.Shuhaiba Backer

10. OTHER METALS
• The earliest collapsible tubes were made of
TIN, ZINC or LEAD, some times coated with
wax on the inside.
