4. INTRODUCTION Strip packaging is an alternate form of pack for a unit dosage. It is a method of enclosing the article concerned between the two web of material so that each is contained between separate compartments. The two web of material may not be necessary to be identical.

5. PROCESS OF PACKAGING Two webs of materials being fed between two heated crimping rollers On which they are circumferential cavities of a size and depth appropriate to the shape, size, and thickness of the article. The article is being packed the material.

6. The material is fed from a hopper through channels to drop between the crimping rollers. The cavities present in the webs are sealed together by the activation of the thermoplastic coating on their inner surface and pockets. At the end, pockets are formed around the contents.

7. DESIGNING OF STRIP Strip design are very basic, as the emerging units are invariably rectangular or square strip. The pockets can round, oval or square shape. The pocket area is depends on diameter, shape and thickness of product.

8. If the pockets is too ‘tight’, it affect the - perforation of pockets - wrinkling of seal If the seal area likely to be wrinkle or crease shown, then wider seals may be necessary. Generally, the width of seal taken as 5mm and above.

9. INSPECTION OF SEAL To check the seal of packaging material either periphery of pockets is perforated or not, the heating of seals are very efficient method. Samples strips are taken at regular interval and exposed them briefly. After that get packaged material immersed in a water to a vacuum of about 680Mb.

10. MATERIAL USED FOR STRIP PACKAGING Material employing foil provides the best, excellent, protection provided and effective seal is achieved. Two plastic pipes, each with a vacuumised foil, when laminated in direct contact with one another, it gives excellent barrier property.

11. PET (POLYETHYLENE TEREPHTHALATE) is very resistant to tear, hence it needs a tear feature and also confers child resistance. The most widely used material for excellent moisture protection are: - Extrusion coated foil(12gram per sq.meter ) - paper with 40-50 gsm .. - Soft aluminum foil (7 – 9µm).
