pharmaceutical shrink packaging (foil, plastic pouches, bottle seals, tape seals, breakable seals, sealed tubes) pharmacy technology packaging covers plastics Shrink packaging Shrink packaging indicates the process in which sheets of transparent plastic film are wrapped around a product to form a solid, weather-resistant packaging layer. Shrink packaging customarily refers to plastic films which have been pre-heated, stretched and cooled prior to use. This causes their initially randomly scattered molecules to align themselves in rigid structures, creating flat sheets of plastic film. Shrink-wrap When the shrink packaging films are applied to the product and re-heated, the molecules revert to their previous non-aligned state. This causes the plastic film to shrink and wrap itself tightly around the form and shape of the product (therefore the name ‘shrink-wrap’). Stretch-wrap When shrink packaging is simply stretched and wrapped around the product without being re-heated, it is known as ‘stretch-wrap’. Benefits of shrink-packaging Shrink packaging offers a versatile, cost-effective packaging solution for several reasons. First, the materials used (plastic derivatives) are strong yet flexible, and provide effective protection, as well as making the product tamper-proof. Second, shrink packaging is transparent, making it suitable for retail and wholesale display, and ideal for general marketing purposes due to its clear surface. Third, shrink packaging is a relatively inexpensive option and ideal for low-cost packaging solutions.

• Shrink packaging
• Foil

• Bottle seals
• Tape seals
• Breakable seals
• Sealed tubes

3. Shrink packaging
• Shrink packaging indicates the process in which sheets of transparent
plastic films are wrapped around a product to form a solid, weather –
resistant packaging layer.
• The shrink band concept makes use of the heat-shrinking characteristics of
a stretch oriented polymer, usually PVC.

4. • The heat-shrinkable polymer is manufactured as an extruded, oriented tube
in a diameter slightly larger than the cap and neck ring of the bottle to be
sealed.The heat-shrinkable material is supplied to the bottle as a printed,
collapsed tube, either precut to specified length or in roll form for an
automated operation.
• The proper length of PVC tubing is slid over the capped bottle far enough to
engage both the cap and neck ring of the bottle.The bottle is then moved
through a heat tunnel, which shrinks the tubing tightly around the cap and
bottle, preventing the disengagement of cap without destroying the shrink
band.

5. How does Shrink packaging system work ?

6. Benefits of shrink packaging
• Shrink packaging offers a versatile, cost-effective packaging solution for
several reasons.
• First, the materials used (plastic derivatives) are strong yet flexible, and
provide effective protection, as well as making the product temper-proof.
• Second shrink packaging is transparent, making it suitable for retail and
wholesale display.
• Third, shrink packaging is a relatively inexpensive option.

7. Foil
• The most commonly used shrink packaging is polyolefin.
• It is available in a variety of thicknesses, clarities, strengths and shrink
ratios.
• Other shrink films include PVC, polyethylene, polypropylene, and several
other compositions.

10. Use
• Food & beverage industry
• Automobile industry
• Pharmaceutical industry
• Chemical industry

11. Plastic pouches
• A plastic pouch is a type of container made of thin, flexible, plastic film.
• Plastic poches are used for containing and transporting goods such as foods,
produce, chemicals, and waste.
• Pouches can be made with a variety of plastics films, polyethylene is the
most common.Others forms, including laminates and co-extrusions can be
used when the physical properties are needed.

14. Uses
• For Drinks and juices
• Packaging of detergents and bleach

15. Bottle seals
• A bottle may be made tamper resistant by bonding and inner seal to the rim
of the bottle in such a way that the product can only be attained by
destroying the seal.
• For pressure sensitive inner seals pressure sensitive adhesive is coated on
the surface of the inner seal as an encapsulated adhesive.

17. Tape seals
• It involves the application of glued or pressure sensitive tape or label around
or over the closure of the package which is to be destroyed to obtain the
product.
• Labels made of self destructing papers are available.
• But these cannot survive any attempt at removal once they have been
applied.

19. Breakable seals
• Breakable closures come in many different designs.
• The roll-on cap design of aluminum shell used for carbonated beverages.
• The bottom portion of the cap is rolled around the bottle neck finish.
• The lower portion of the cap blank is usually perforated so that it breaks
away when the cap is unscrewed.

21. Sealed tubes
• Collapsible tubes used for packaging are constructed of metal, plastic or
lamination of foil, paper and plastic.
• Metal tubes are still used for products that required high degree of barrier
protection.
• Most of these are made of aluminum.
• Extruded plastic tubes are widely used for products that are compactable
and limited protection of plastic.
