Polyethylene packaging is one of the most common household items. This material began to be produced only 60 years ago, and it did not always have modern qualities. Let's reveal some interesting facts about such a well-known thing
1. Not only packaging
Initially, plastic bags were made for storing bread and other flour products, vegetables and fruits. Handles of such bags appeared only 25 years later. For a long time, bags served only one function - packing. Today the packages are of an informational and advertising nature.
2. Uncomplicated production
Polyethylene packaging is made using special materials and equipment. Equipment for the production of plastic bags is reliable, compact, easy to operate, consumes a small amount of electricity:
- Extruder - a device that processes raw materials and makes a plastic film or sleeve;
- Flexographic machine - used for printing on products;
- Equipment for cutting film for bags and cutting the product of handles.
3. Two main types of material
The bags are made from first grade polyethylene granules or recycled materials. The material for making bags is divided into:
- High pressure polyethylene (LDPE). This material was originally used for insulation. Polyethylene does not emit toxins into the environment, it is safe for humans upon contact. Perfect for storing food. Possesses high strength, resistance to temperatures and weather conditions.
- Low pressure polyethylene (HDPE). This material, in comparison with LDPE, is more durable and less susceptible to mechanical stress.
The choice of material for the manufacture of bags depends on the scope of destination of the finished product.
4. Valuable benefits
Plastic bags have a number of advantages:
- Availability and low price
- Ease of use
- Good hygienic properties. The bags can store food, which will significantly extend the shelf life of the product.
5. Typology of packaging
Polyethylene packaging can be divided into three groups:
- By type of print
- By type of production
- By the shape of the handles
6. Types of packages
- Packing package. We meet this type of packaging every day. Retail chains use this type of packaging to separate and protect goods from contamination. Fruits, vegetables, various bulk products are packed using this type of packaging;
- T-shirt package. One of the most popular types. Due to its shape, property and type of handles, such a package can withstand a fairly large weight, and the arrangement of the side walls helps to change the package in volume and have a good capacity;
- Banana bag. Packaging with handles. This type of package is used to advertise products. Polyethylene does not have sufficient strength and capacity.
- Bag with loop handles. The only thing that distinguishes this type of packaging from a banana bag is the type of handles. The handles are not cut out, but taken out and attached to the bag with special seams.
- Advertisements are applied to banana sacks and sacks with loop handles. On this type of packaging, the image looks best - without creases and bends. Advertising packaging is used at various exhibitions to present products and attract new customers.
