INTRODUCTION
The laminated tube is created bringing together the advantages of
both aluminum and plastic. Laminated tube suppliers in India, like Sorbead
India, make use of the latest technology to create a tube, which 1) offers
protection against light, air and humidity, 2) provides sufficient space for
graphics and lastly 3) has the most aesthetic minimal seam.
Laminated tubes find the maximum use in the pharmaceutical
industry. High-end laminated tubes are mainly used to pack medicines that are
in gel form. As they are manufactured as gels, one needs to be extra careful
while packing and transporting these medicines as the chances of them getting
spilled over are very high. This is where laminated tubes prove useful as their
high gloss protective lacquer will keep the medicine safe and unadulterated. In
the market, laminated tubes are available in many graphic modes and in different
sizes and styles. There is something for everyone in the wide range of
laminated tubes up for offer.
HOW LAMINATED TUBES ARE
MANUFACTURED
Now let us understand the manufacturing process of Laminated Tubes. They are made from a poly- foil-poly premise having polyethylene on both
sides of a light gauge of foil. In some
cases, paper is also used. In the first step, the laminate feed-stock material
is enhanced by using letterpress or
rotogravure printing.
Next, the laminate tubes are created by placing the laminate
material rolls onto the machine. Then the material is transferred onto a flat
state and moved through forming rolls where the tubes are shaped into different
sizes, as per the demand. It then passes through hot temperatures, which joins
the sides together to create the final cylindrical tube. In the third step, the
tube moves towards the heading operation section where the preformed head and
shoulder are attached to the tube top.
This is done using heat generated from high-frequency energy.
The last stop is the capping section where the cap style, be it
flat, fez or pedestal, is finally decided upon. Once the cap is fitted, it is
torqued according to customer requirements. Then the tube moves towards packing
and is finally ready to be used.
Advantages of Using Laminated Tubes
As mentioned earlier, the main benefit of using Laminated Tubes is
that it combines both the positives of plastic and metal. The tube material is
like plastic and has the tough barrier properties of alumina. The latter
prevents contact with air, strong light and moisture, which can render the
product useless. Laminated tubes also act as a strong barrier against dust
particles and wind. They too can spoil the gel/ointment stored inside.
Another major advantage of these tubes is that they
are tamper-resistant and have a good “feel” about them. This good “feel”is
maintained throughout the shelf life of the product. Most pharmaceutical opt
for laminated tubes as they are lightweight, hygienic and toxin-free. The low
cost of manufacturing is also an added bonus that customers make a beeline at
the suppliers of laminated tubes.
