Different Types of Packaging Materials

By Shailesh Jadhav

Classification of Material used for Packaging

SELECTION OF PACKAGING MATERIAL The materials selected for packaging must have the following characteristics: 1. They must protect the preparation from environmental conditions. 2. They must not be reactive with the product, 3. They must not impart tastes or odours to the products, 4. They must be non-toxic, 5. They must be FDA (Food & Drug istration) approved, 6. They must meet applicable tamper-resistance requirements 7. They must be adaptable to commonly employed high-speed packaging equipment. and

Application of Paper for packaging: • • • • • • • • • • • • •

dry food products – e.g. cereals, biscuits, bread and baked products, tea, coffee, sugar, flour, dry food mixes frozen foods, chilled foods and ice cream liquid foods and beverages – milk, wines, spirits chocolate and sugar confectionery fast foods fresh produce – fruits, vegetables, meat and fish personal care and hygiene – perfumes, cosmetics, toiletries pharmaceuticals and health care sport and leisure engineering, electrical and DIY agriculture, horticulture and gardening military stores.

The main types of paper and paperboardbased packaging are: • bags, wrappings and infusible tissues, for example tea and coffee bags, sachets, pouches, overwraps, sugar and flour bags, carrier bags • multiwall paper sacks • folding cartons and rigid boxes • corrugated and solid fibreboard boxes (transit or shipping cases) • paper-based tubes, tubs and composite containers • fibre drums • liquid packaging • moulded pulp containers • labels • sealing tapes • cushioning materials • cap liners (sealing wads) and diaphragms (membranes).

Paper is used for the packaging due to the following advantages: Flexible in nature, Easy amenable to printing, Easy amenable to any kind of coating, Good temperature resistance either high or low, Excellent properties towards recycling, High strength properties Good insulation properties, High gloss properties on smooth side (i.e. felt side), Could be manufactured with high brightness properties, Excellent folding endurance properties, Good tear resistance properties and Compatibility with other packaging materials for lamination.  

Properties of Paper Board Paper boards are having all the properties of paper, In addition, these materials are having good dead fold characteristics, High stiffness properties, Amenability to fabricate folding cartons, display carton, etc. and Less cobb value as compared to paper.

Types of Paper and Paperboard

Solid bleached board (SBB): Paperboard made from virgin bleached chemical Pulp.

Solid unbleached board (SUB): Paperboard made mainly from unbleached virgin chemical pulp. A layer of bleached fibre is sometimes added to the top to provide greater whiteness

Folding boxboard (FBB): This paperboard is made from a layer or layers of mainly virgin mechanical pulp sandwiched between layers of virgin chemical pulp. The top layer is bleached chemical pulp and the bottom layer can be either bleached or unbleached virgin chemical pulp

White lined chipboard (WLC): This is made from multi-layers of recycled fibres. The top layer can be made from bleached virgin chemical pulp or white deinked recycled fibres. Between the top layer and the middle layer(s) there can be a layer of chemical, mechanical or deinked recycled fibres. The bottom layer can be made from selected recycled or bleached and/or unbleached virgin fibres

These are light weight papers with the GSM of 12 to 30. It is used for tea and coffee bags. Wrapping tissues may be white or colored as the chief use is fancy wrapping. The important characteristics are toughness, even formation, finish and anti –tarnish properties. Tissues are made from bleached and unbleached wood pulp, rags and other best fibers. These papers are also used for wrapping jewelry, silver wares etc.

Greaseproof paper is made under hygienic condition from pure wood pulp which gives excellent grease resistance and oil hold out properties. Paper prevents penetration of oil & fats thus retain the original flavor and taste intact. No negative effect on original quality of food since paper has good breathability. Greaseproof paper is suitable to withstand wide range of environments, from hot oven to deep freezer & humidity. Range of GSM is 30 to 70. Features Excellent grease resistance and oil hold out properties. Machine friendly for printing and converting. High strength & Stability. Withstand in Oven & freezer. End Use Fast food items packaging like Burger, French fries, Snack Rolls, & other oily food products. wrapping of meat, fish and cottage cheese.

Glassine:

It is a super calendared greaseproof paper looks smooth, dense and transparent/semitransparent. It gives high resistance to air and vapor age. It may be laminated or metalized to protect food stuffs, chemicals etc. It may be used as carton linear. The range of GSM is 30 to 80.

Kraft: It is a strong paper mainly used for wrapping, packaging, sack bag etc. GSM range is 70 to 100.It plays important role in whole distribution system. An important class of Kraft paper is sack Kraft. This paper is used for making bags for various materials like cement, sugar, chemicals etc.

Vegetable Parchment:

This paper has high grease resistance and wet strength due to sulphuric acid bathing and gelatinization. This paper can be used in deep freeze and in both conventional and microwave ovens. It can be silicon treated for product release. GSM range is 30 to 230.

Vegetable Parchment paper is manufactured with chlorine free highly refined pulp to develop excellent water proof and fat resistant properties. It remains odorless when left wetted for long time. Paper is free from any impurities like starch, gelatin, casein, formaldehyde or loaded material etc. Features Paper is with high density, stability, and excellent grease and moisture resistant. High Oil Kit Value. High Wet strength. Machine friendly for printing and converting. End use The Butter and Margarine packaging. Food wrapping and cheese wrapping.

Duplex Board: It has two different stocks laminated together. Top layer is made up of superior chemical wood pulp and bottom layer is of waste paper and mechanical pulp. This board offer better printing finish on top and protection in inner side as well as economical. These boards are used to make folding cartons of sweet boxes, medicines etc. (230 420 gsm) Ivory board High quality board made in white or colors with a bright, clear appearance, particularly used for visiting cards and similar high class printed work Original Ivory Board was and still is made in Holland, although the grade is now made in many countries (200 400 gsm) Pulp Board: They are manufactured from one type of pulp and used for making boxes where cleanliness and strength is important. These boards are used for manufacturing solid fiber box liner and folding cartons. Corrugated Medium: These boards are exclusively used for making corrugated fiber

Linear Boards: These are strong homogeneous boards used for corrugated and solid fiber board inner and outer facing. It acts as good binder as well as gives resistance towards hard usage. Mill Board: These boards are thick and made from waste paper and screening. They provide good stiffness. These boards are used for binding and containers. Grey board: These boards are better than mill board in quality and have less thickness. These boards are also manufactured from waste paper. These boards are extensively used for packaging shoes and parts of machinery. Straw Board: These are made from grasses, bag a sea and straws. These are extensively used for book binding, textile industry and boxes.

Limitation of Paper based Packaging Material

Folding Cartons Advantages: Economical in cost, Easily fabricated and assembly Collapsible Good Printability and Embossing Attractive design, value added feature, and Sales appeal Versality Special feature-Window, Fresnel lens, Drip off effect

Folding Cartons Disadvantages: Flimsy compare to set top box, plastic container, Not suitable for heavy or bulky object.
