Liquid products packaging

PACKAGING OF SOLID AND LIQUID PRODUCTS AND HANDLING OF PACKAGES... 

BIB refers to a sealed, sprouted (small too large, with or without dispensing valves) plastic film bag inside a molded rigid container, generally for packaging liquid products. Outer box may be made of disposable corrugated cardboard, disposable or reusable... 

Some inventory of finished product must be held to match production with sales. Provision for product packaging and transport will also be needed, depending on the nature of the product. Liquids will normally be dispatched in drums and in bulk tankers (road, rail and sea), solids in sacks, cartons or bales. 

Glass-packaged liquid products may break owing to the volume expansion of the solution when it freezes. It is especially important that the pharmacist fully advise the patient on proper storage and use of ophthalmic products to ensure their integrity and their safe and efficacious use.

Economics, As with the alkyltin stabilizers, the market pricing of the mixed metal stabilizers tend to be directed by the particular application. The calcium—zinc and barium—cadmium packages are typically used at 2.0—4.0 parts per hundred of PVC resin (phr) in the formulation. These completely formulated products are sold for 2.50— 4.40/kg for the liquid products and 3.20— 6.50/kg for the solids and pastes. The higher efficiency products aimed at rigid applications tend toward the higher end of the cost range. 

Typical brick-shaped cartons (aptly named briks ) are synonymous with the name of TetraPak and TetraBriks. Laminated board cartons have been available for 70 or more years for liquid products (Figure 9.6). Developed in the dairy market, they are a major packaging format for still drinks some markets are dominated by the single-serve brik and others by the multi-serve version. The other significant factor for these drinks cartons is that the system is available worldwide, making global production of new products much easier. 

The development of aseptic technology has radically opened up new possibilities for efficient and economical handling of perishable liquid products. Aseptically processed and packaged juices will keep for months at room temperature in sealed packs. The key advantages of aseptic cartons are that... 

Due to its particularly good polymer characteristics PVC has an enormously wide spectrum of applications. From the consumption of more than 5.5 x 106 t in Western Europe (1997), 60% is in the building field, with a tendency to rise. Blow molded containers for packaging liquid products (beverages, edible oils, detergents, cosmetics and pharmaceuticals) receive special consideration, as do dishes for fatty foods (highly...
