Here you will find some general information about packaging:
under This and That you will find information on various packaging functions, such as:
"Many products, especially food, may not be stored, distributed or sold without packaging. Packaging forms a unit load of one or more product units (engl. Unit load, see Glossary of logistics), thus supporting the processes of logistics and trade. It has to fulfil several functions:
Primarily packaging shall protect the product itself from environmental influences, damage, contamination and loss of volume. In addition, packaging also protects people against physical injuries caused by sharp-edged goods, spiky or toxic objects. Furthermore, means of transport, environment and other goods are protected from damage, for example caused by leaking liquids. Another issue is the preservation of food, for example by airproof packaging. Aseptic bottling system, sterile bottling, or protective gas (or vacuum packaging) are common methods.
From the time of production up to the time of use or consumption all merchandise is placed into stock and relocated several times. Thus, all merchandise can be stored by the manufacturer or importer, in the wholesale and retail trade, by the forwarding agent or stock keeper and by the consumer. With the help of appropriate packaging goods can be stored easier, safer and faster.
Loading and transport function
During transport packaging shall prevent the goods from being subjected to excessive stress. This can be done by using a multiple protection (cardboard box + pallet). Moreover, standardized packaging involves less space requirement on the respective means of transport. Standardisation can even go as far as to adapt the dimensions of the packaging material (e. g. pallets or drop-side mesh pallets) exactly to the dimensions of the means of transport, thus leading to an optimal load of the means of transport and an acceleration of the loading and unloading process. These facts are displayed by the DPR model.
Sales packaging as an advertising medium
A sales package allows the buyer to recognise the product, whether by its name, its logo, its colour or by the shape of its packaging. An attractive sales package promotes sales, thereby improving the product’s distribution and acquiring new customers. Quite often a sales package provides the first impression decisive for buying a product.
Sales packaging as a means for rationalising the selling process.
Only by using modern packaging methods the self-service system experienced its upswing. For example, the weighing and packaging of the required product at the counter of the butcher’s shop is inapplicable if it is previously packed, weighed and pre-priced, then being available for self-service.
Polyamide. The term "polyamide" normally refers to synthetic, technically utilisable thermoplastic materials and distinguishes this group of materials from those with chemically-related proteins. Most polyamide production is used as synthetic fibre in the manufacture of textiles. Typical examples of polyamide use are fishing lines, brassieres, lingerie, overalls and smocks, bathroom sponges, strimmer blades, nylon stockings, rainwear, ropes of all sizes (climbing ropes, tug boat hawsers), guy ropes, trampoline safety nets, industrial fabrics for the paper industry, tennis racket strings, wall-to-wall carpeting, sportswear (especially gym shorts and training suits), jackets for military use (flying jackets, parkas, etc.), techno clubwear, etc.Polyamides are also used in unbreakable household items, abrasion-resistant parts and components such as Rawlplugs, screws, covers and casings, sliding contact bearings, electrical insulation, cable ties, adhesive mounts, medical tent jointing parts, kitchen utensils (spoons, ladles, etc.), machinery parts (covers, gear wheels, bearings and castors) and the bristles of toothbrushes.Due to its resistance to fuels and lubricants at temperatures in excess of 150°C, polyamide is found in the components of vehicle engine intake and fuel systems and engine covers.

Polyethylene (PE for short and sometimes referred to by its former name "polyethene") is a thermoplastic material obtained by the polymerisation of ethene [CH2 = CH2] and has a simplified chain structural formula.Polyethylene belongs to the polyolefin group of materials.Some well-known polyethylene trade names are Alathon, Dyneema, Hostalen, Lupolen, Spectra, Trolen and Vestolen.

Polypropylene (PP for short and also known as polypropene) is a partly-crystalline thermoplastic that belongs to the polyolefin group. Polypropylene is obtained by polymerisation of the monomer propene with the help of a catalyst. 30 million tonnes of polypropylene were manufactured in 2001 In PP, strength, hardness and stiffness are greater than in polyethylene, but less than in other plastics, such as polyamide.PP is found in many products in the food processing and household equipment industries, as well as in packaging technology; it is typically used in the manufacture of bottle tops, dishwasher components, containers (boil-proof, re-useable and isothermal containers (EPP)), drinking straws, packaging components etc.

Polystyrene (PS for short, IUPAC designation: polystyrene) is a transparent, amorphous or partly-crystalline thermoplastic. Amorphous polystyrene is widely distributed and is found almost universally in everyday use.Polystyrene is used either as a thermoplastic material or as a foam. Some well-known trade names for polystyrene are Lustron, Styropor, Styrodur, Styroflex, Sagex (in Switzerland) und Telgopor (in Spanish-speaking countries).

Polyvinylchloride (PVC for short) is an amorphous thermoplastic. It is white in colour, hard and brittle, though it can be made softer (and for industrial purposes more workable) by the addition of stabilisers and softening agents. PVC is mainly known for its use in floor coverings. It also plays an important role in the construction industry, where it is used for the manufacture of pipes, tubing and window frame mouldings.
Due to its low weight, PVC is used in low-energy packaging (lower fuel consumption during transportation) and vehicle parts (weight-savings leading to lower fuel consumption).
