TYPES OF PAPER & FOLDING CARTON used in pharmaceutical companies : TYPES OF PAPER & FOLDING CARTON used in pharmaceutical companies Presented By: Sumit Kumar Mittal I.S.F College Of Pharmacy, Moga (Punjab) DEPARTMENT OF QUALITY ASSURANCE OBJECTIVE : OBJECTIVE Physical protection Barrier protection Agglomeration Information transmission Marketing Convenience Portion control Types of paper : Types of paper Kraft paper used as outer facing far corrugated , spirally wound kegs and fiberboard drums Uncoated paper , usually from highly-grade chemical pulp source , used in the calipers far small labels and leaflets One side coated are used far the heavier weighted labeling material Two side coated lighted paper are pores between the fibers achieved by beating the fibers far very long time Types of paper : Types of paper 3) White wood-free paper for laminates is usually one-side coated paper that has been super- calendered to make the outside (coated) surface less permeable. 4) Vegetable parchment paper is made by a process of treating the absorbent paper with sulphuric acid, which enhances the wet strength of the paper. This is the most water-resistant paper of all. It is usually used for ‘dressing’ packs. Fibers for Papermaking: Fibers for Papermaking Fibers are defined as “...tough threadlike substances capable of being spun or woven, whether they be natural (vegetable, mineral, animal) or man-made .” Four Types of Cellulose Fibers: Four Types of Cellulose Fibers Bast Fibers Seed Hair Fibers Cotton fibers Flax plant Only 5% of the flax plant is usable for paper manufacturing Grass Fibers Wheat straw Bagasse fiber (extracted from sugar cane stalks) Esparto grass Kenaf plant Wood Fibers Manufacturing process: Manufacturing process Pulping Machine conversion in to paper Pulping : Pulping The objective of pulping is to separate the wood into individual fibers. Three broad classifications of pulping methods: Mechanical ( groundwood ) Chemical Combination ( chemi -mechanical) Chemical pulp: Chemical pulp This process separates each fiber from its bonding material—lignin. The adhesive qualities of lignin holds cellulose fibers together. Bleaching: Bleaching The purpose of bleaching is to remove stains caused by lignin. Major bleaching agents chlorine, sodium hypochlorite, hydrogen peroxide, chlorine-dioxide, and oxygen. Fourdrinier Paper Making Machine: Fourdrinier Paper Making Machine Nicolas Louis Robert invented the papermaking machine in 1798. Sealy Fourdrinier and Robert improved the original design of the papermaking machine to produce paper with a felt side and a wire side. The paper is formed at the wet end of the machine—after the pulp-water mixture has been refined. Fillers Coloring material Sizing Paper Making Machine: Paper Making Machine G. Headbox H. Fourdrinier I. Presses J. Dryers K. Size L. Dryers M. Calender -Reel N. Winder Press The Headbox: The Headbox The head box spreads pulp and water mix evenly over the moving wire. The pulp-water mixture containing the added fibers, coloring material and size is diluted with water to make “slurry” containing ½ % to 1 % of cellulose fibers. The Fourdrinier Wire : The Fourdrinier Wire The fourdrinier wire causes the forming of paper at the wet end of the machine. It is the section of the papermaking machine made up of a fine woven screen to let water drain away causing the pulp to remain to form a thin mat. Synthetic plastic fiber wires are used in modern papermaking machines. When the mat had left this stage of production it contains 75% water. Presses: Presses During this stage of production, the mat enters wet rollers carried by felt blankets to reduce the amount of water to 60 - 65%. It is during this stage that the thin mat or paper begins to form a web or long ribbon. The paper continues through press rolls and felt blankets to remove water. Dryers: Dryers Steam heated cylinders dry paper to 5% moisture. SIZE PRESSES Steam heated cylinders dry paper to 5% moisture. DRYERS Second dryer unit removes moisture applied to sheet in size press. Calender-Reel: Calender-Reel Polished rollers iron and control thickness of sheet. Reel winds paper on mandrel. WINDER Winder unwinds paper from mandrel, passes sheet across slitter to trim edges and cut paper to final width. Twin Wire Machines: Twin Wire Machines This method of papermaking was developed to improve the efficiency of the fourdrinier design. Cylinder Machine: Cylinder Machine This type of machine is designed for making extremely heavyweight paper and/or multi-ply products used in the manufacture of corrugated containers, folding cartons, and solid fiber boxes. Two types of cylinder vats Contraflow Direct flow. Folding Cartons: Folding Cartons Folding Cartons: Folding Cartons These difficult to handle, temperamental objects in white lined folding boxboard are popular in the industry because they are good at their job, which is to contain, protect and distinguish the product from all others in an economical manner. They are sometimes known as ‘secondary’ packaging Choice of design: Choice of design Pharmaceutical products and with the necessary levels of hygiene control, QC, and inspection . Style Types of board Layout Origination: Origination Cutting and creasing formes—These are the cutting (sharp) and creasing (blunt) knives fitted into a sheet of thick plywood Plates—Need to be made from the artwork, Cost of origination ---This entails looking to the best way of minimizing the costs of artwork, plates, printing processes PowerPoint Presentation: It ready for production, including the selection of the board sheet size. Printing May use either a four colour process system (cyan, magenta, yellow and black), or a multi-colour system. The most common methods of printing today are all sheet fed, mainly using letterpress and offset litho. Cutting and creasing: Cutting and creasing The basic purpose is to stamp in the crease lines, at the same time cutting out the outline of the carton. The prime reason for creasing the carton blank is to define the shape of the carton panels and allow it to fold without distortion. Pre-folding and gluing: Pre-folding and gluing Cartons are usually supplied in a collapsed state, with a glued side seam and two of the folds already made. Gluing the carton is usually compressed to a flat state where it already exhibits some degree of ‘crease set’. Carton erection and filling: Carton erection and filling The action of mechanically erecting, inserting primary pack, insertion of leaflet, then the closing of the carton is another world in which technical expertise may be required. Automatic: Automatic There are two basic types of machine— i ntermittent motion and continuous motion . The intermittent is the smaller, slower and cheaper, usually with a blade opening action for the carton pre-break, so that it is likely to accept a lower quality of carton pre break, than the really high-speed machines. The continuous motion machines tend to be much larger, faster and more expensive and, being much faster with vacuum pick-up of the carton for a ‘knock’ pre-break, are much more sensitive to the quality of the carton presented. Semi-automatic: Semi-automatic This is usually a machine where the carton is erected, the bottom closed and the top opening presented to the operator who drops in the goods and any accessories. It would be expected for this type of machine to have an overprinting unit of some type built into the cartoning machine.
