Packaging Printing

The main purpose of printing and packaging is to hold its contents securely to prevent leakage and breakage, protect foodstuffs against various risks such as microbes, the moisture loss of heat, humidity or pick , etc., to protect content while distribution, etc. For all types of packaging, there are different types of packages. The different types of packets can be classified into two groups:

Retail containers: The containers protect the food or the contents of different damages and at the same time they advertise the product for retail sale. For example, glass bottles, bags, over wraps, plastic bottles, cans, etc. They can be used for storage of the house too.

Shipping Containers: The containers contain and protect food and other items during distribution and transport or marketing function. For example, bags, stretch or shrink wrapped containers, corrugated board fire, drums, barrels, crates and bags with foil.

industrial packaging materials are different from traditional packaging materials. Different types of industrial packaging materials include:

Metal containers: Two types of metal boxes are used such as, double stitched, which are used for the manufacture of cans and metal containers with push on lids that are used to store dry foods such as coffee powder, milk powder, dry yeast, etc. double seamed cans are made of aluminum or tinned steel that are lined with special paints suitable for different types of food. The cans are widely used because they offer many advantages. They can give full protection to food. They are inviolable and can be made in different shapes and sizes. At the same time, they have some drawbacks as they are heavier than plastic and therefore high transport costs. large metal drums are used as containers for transporting oil, juice and many other liquid foods. The aluminum metal containers are very useful because they are impervious to moisture, microorganisms, lights, odors, etc.

Glass containers: glass bottles and jars are very popular for food packaging. They protect food from moisture, pests and micro-organisms. They are very useful as they can be processed by heat, reusable, recyclable, rigid, can be stored and are transparent to view its contents or food inside. With various advantages it has some drawbacks too. They are heavier and therefore require higher transportation costs. They can be easily broken, especially when transporting by road accident. They are mainly used for packaging foods such as various preservatives such as jams, jellies, juices, pickles, beer, wine, etc.

Paper and paperboard containers, paper and cartons are primarily made from wood pulp and other additional elements to be taken in a suitable container. Different types of paper used to wrap food. For example, documents sulfate is used as a paper bag for fruits, vegetables, flour, sugar, etc. small tanks cartons or bags may be used for confectionery, snacks and nuts. Whiteboards are suited to ice cream, chocolates, and cartons frozen because they are covered with wax or plastic for making heat sealable container. chipboard cartons are used as the outside, especially for tea or cereals but not in contact with food.

The plastic films: flexible plastic films are relatively mild. They protect food and other materials from heat, gas and moisture. They add little weight to the Food and adjusting the shape of the cargo. They do not take much space and they have strength dry and wet which makes them convenient for the consumer, the manufacturer and the retailer. Foods such as milk are packaged in flexible plastic film.

Polyethylene: less expensive than other packaging materials, they act as a good moisture barrier, but not a good odor barrier. high density polyethylene are thicker, stronger and better barriers to moisture and gases.

There are many other types of packaging such as polypropylene, coated films, laminated films, coextruded films, rigid and semi rigid plastic containers and much more. Each of these containers have individual advantages and inherent quality.
