LDPE or low density polyethylene, colloquially called plastic, is the most widely used plastic in the production of packaging. Its property can be corrected by various additives: strength or shrinkage. It can be used for a whole range of packaging. We use it for the production of common carrier bags, bags for industrial production, bags, e-commerce bags with adhesive strip, boundary tapes. For e-commerce bags, we recommend the so-called BI-LDPE, a two-layer foil - white on the surface, black inside, which prevents the contents inside the bag from shining through. LDPE foil is odorless and tasteless. The foil can be colored, but today full-area printing is preferred. Heat resistance is from -50 °C to +85 °C. Clear foil is suitable for contact with food. Products can be recycled or disposed of by incineration. The recommended thickness of conventional bags is about 50 microns.
High density polyethylene (HDPE) is a thermoplastic invented in 1957. HDPE foil has been produced in Czechoslovakia since 1976 under the Mikroten brand, which has become synonymous for HDPE. HDPE bags and sacks are among the cheapest packaging materials. They are well recyclable, storable and suitable for contact with food. 15-20 micron foil is usually used for the production of bags. Foils with thicker thickness can be used for the production of luxury bags.
Biaxially oriented polypropylene film (BOPP) is widely used, for example, in food packaging (especially pastries and sweets), boxes (CDs, tea, coffee), perfumes, magazines, textiles, books, etc. The foil is most often used for packaging on packaging or folding machines. It is strong with optimal breathability, resistant to temperature fluctuations and humidity, suitable for contact with food with high weld strength. Transparent color allows visual inspection of packaged goods, it is very easy to print even with demanding prints.
