WHAT ARE ANCILLARY PACKAGING MATERIALS?
Secondary packaging material Add value to primary package Improve performance Absence or inadequacy, impairs the performance of primary package S.K.SARAVANA,

HOW DO THEY ADD VALUE? Prevent contamination Enhance visibility Bind packaging materials Improve strength Prevent product damage Hold system together S.K.SARAVANA,

CAPS AND CLOSURES S.K.SARAVANA,

CAPS AND CLOSURES MAJOR CLOSURE SYSTEMS: Lids Aerosol valves Threaded closures Crowns Lug caps S.K.SARAVANA,

FUNCTION OF CLOSURE SYSTEM
Product protection spoilage & contamination in storage & transportation Preservation of product over stipulated time A) Providing barrier to moisture, air, gases, vapors of volatile liquids B) Holding vacuum and pressure C) Preserve organoleptic properties Protection against pilferage, tampering & adulteration Provide ease of opening & resealing Provide convenience in dispensing S.K.SARAVANA,

THE CLOSURE SHOULD… Not hinder dispensing Neither affect nor get affected by product Not release any toxic ingredients into the product Withstand processing, sterilizing, pasteurizing, autoclaving etc. i.e., steps that may be involved in its life-cycle. S.K.SARAVANA,

FACTORS FOR SELECTION OF CLOSURES
Product characteristics Dispensing mechanism Compatibility Dimensional stability Environmental stress cracking resistance Heat resistance Thread matching tolerances Cost S.K.SARAVANA,

RAW MATERIALS FOR CLOSURES…
PLASTICS PP LDPE HDPE S.K.SARAVANA,

GLASS S.K.SARAVANA,

METALS S.K.SARAVANA,

INKS S.K.SARAVANA,

INKS Inks are colored liquids or pastes, formulated to transfer and reproduce an image from a printing surface Components of Inks: Pigments/dyes, vehicle, solvent & additives Convey a message Give a decorative effect to the substrate Inks are used on a wide range of papers, boards, plastic, glass and textiles surface S.K.SARAVANA,

FORMS OF INKS SOLUTION PASTE POWDER S.K.SARAVANA,

TYPES OF INKS Printing Inks Rotogravure Inks Flexographic Inks Offset Inks Screen Inks Specialty Inks Marking Inks Night Glow Inks Textile Inks UV Inks Fluorescent Inks Surface Coatings S.K.SARAVANA,

SELECTION OF INK Types of printing process Type of substrate Application Finish Drying process S.K.SARAVANA,

ADHESIVES S.K.SARAVANA,

ADHESIVES Adhesive/glue is a mixture in a liquid, semi-liquid, solid state that adheres or bonds items together Adhesives come from either natural or synthetic sources Used to bind similar and dissimilar materials S.K.SARAVANA,

CLASSIFICATION OF ADHESIVES
ON BASIS OF SOURCE: Natural: Starch, dextrines, animal and plant proteins, natural rubber, shellac Semi-synthetic: Cellulose nitrate, polyamide derivatives Synthetic: Neoprene and PVA adhesives. S.K.SARAVANA,

CLASSIFICATION OF ADHESIVES
Waterborne Adhesives Solvent–borne Adhesives Hot–melt Adhesives S.K.SARAVANA,

WATER-BORNE ADHESIVES
Largest volume class of adhesive used in packaging General advantages of ease and safety of handling, energy efficiency, low cost and high strength Common waterborne adhesives: Starch adhesive S.K.SARAVANA,

SOLVENT–BORNE ADHESIVES
Adhesives in which volatile organic compounds are the major solvent or dispersant Solvents: Heptane, toluene, n-butyl acetate, acetone, methyl ethyl ketone, naphtha, mineral spirits and methylene chloride Factors of cost, safety, productivity and above all, compliance with clean-air law have led to decline in use of these adhesives Commonly used adhesive: Polyurethane adhesives S.K.SARAVANA,

HOT–MELT ADHESIVES Hot melts - 100% solids adhesive Based on thermoplastic polymers that are applied when heated in the molten state and set to form a bond on cooling and solidification Fastest growing important class of adhesives in packaging S.K.SARAVANA,

HOT–MELT ADHESIVES Co-polymer of Ethylene and Vinyl Acetate (EVA) Excellent balance of molten stability, adhesion and toughness over a broad temperature range and compatibility Advantage: Rapid rate of bond formation, which can translate into high production rates on a packaging line. S.K.SARAVANA,

FEATURES OF A GOOD ADHESIVE
The adhesive must retain tack after solvents are removed to wet the secondary substrate The adhesive must be flexible and retain elasticity even after it has cured It should not become hard and brittle The cured adhesive must possess the required level of thermal and chemical resistance The cured adhesive must also be transparent and colorless S.K.SARAVANA,

ADHESIVE TAPES S.K.SARAVANA,

ADHESIVE TAPES Combination of an adhesive and a backing material Available in rolls of fixed length and width Classification of basis of backing material: Fabric tapes, paper tapes, film tapes, non-woven fabric tapes, foil tapes, foam tapes, reinforced tapes, two faced tapes Classification of basis of application: Packaging tapes, hospital and first-aid tapes, graphic art tapes, electrical tapes, automobile industry tapes etc. S.K.SARAVANA,

ADHESIVES USED IN TAPES
Rubber based adhesives: Advantages: Relatively cheap, high tack and adhesion, easy to formulate Disadvantages: Softens and flows at high temperature Acrylic based adhesives: Advantages: Excellent adhesion and stable at relatively high temperatures Disadvantages: Costlier Silicon based adhesives: Advantages: Good tack, withstand temperatures beyond 155oC Disadvantages: Very Costly S.K.SARAVANA,

REINFORCEMENTS S.K.SARAVANA,

REINFORCEMENTS Reinforcement: Enhance strength of packaging Better ability to withstand rough handling conditions Classification: Metallic: Round wires and steel straps Non-metallic: Polyester, Nylon, polypropylene, rayon. S.K.SARAVANA,

FUNCTION OF STRAPS Secure a handling base (skids, platforms, pallets, runners, spacers, etc.) to a unit Strap may be used for local securement or within the transport vehicle Straps also provide security against accidental loss or theft of the contents Different packages can be color coded with strapping for easy identification in warehouses. S.K.SARAVANA,

PROPERTIES OF STRAPS Strength Working range Retained tension Elongation recovery Surface slipperiness Abrasion resistance Split resistance Joint/weld strength S.K.SARAVANA,

FOR BEST RESULTS Use correct quality of straps and seals Use proper size of straps and seals Locate the strap on package correctly Use edge protection material as required Use proper tools and equipments Provide proper tension levels S.K.SARAVANA,

CUSHIONING MATERIALS S.K.SARAVANA,

CUSHIONING MATERIALS Protects the article from damage due to shock and vibration During transport, package is subjected to vibration, movement and jolts Cushioning material prevents product damage, abrasion of surfaces, friction over sharp projection Cushioning materials: Foams, paper shreds, cotton waste, sand etc. S.K.SARAVANA,

FUNCTIONS OF CUSHIONING MATERIALS
Shock protection Protection of high-finished surface Protection of small projection on articles Filling of void space S.K.SARAVANA,

CLIPS S.K.SARAVANA,

CLIPS Used to retain tension Used for reinforcement Types: Metal and plastic S.K.SARAVANA,

LABELS S.K.SARAVANA,

FUNCTIONS OF LABELS To identify the product Provide ingredients Purpose/use of the products Providing aesthetic appeal Child safety Other information like maximum retail price (MRP), Batch No, Shelf-life/Best-before date etc. S.K.SARAVANA,

TYPES OF LABELS Adhesive labels Shrink/stretch sleeve labels In-mould labels S.K.SARAVANA,

RAW MATERIALS OF LABELS
Metals BOPP OPP PP PE PVC S.K.SARAVANA,
