Applied Technology

1
Ultra-fine foam film technology

It is a functional film material imparted with physical properties such as light weight, stretchability, and elasticity,
which is a film containing bubbles that are made by foaming a polymer during the extrusion process of forming a synthetic resin film.
Depending on the characteristics of the fine foam, various applications such as heat insulation, sound insulation, and cold retention are possible.

2Eco-friendly biodegradable film technology

Biodegradable film refers to a film material that is completely decomposed into carbon dioxide and
water by hydrolysis and biodegradation by various types of microorganisms existing in the natural world.
It is integrated into the natural system. Samdong Industrial's biodegradable mulching film is a film that is 100% naturally degraded
by microbial enzymes as it proceeds with soil reclamation through a rotary without removing the film after harvesting various crops.

3PCR recycled material technology

It is a recycled material that is put into production again through reprocessing of waste plastic and waste film. Samdong Industrial recycles PE
used through the casting extrusion process and proceeds with mass production as a stretch wrap film. It is a functional PCR stretch wrap
film manufactured using a casting extrusion process with a world-class 7-layer structure that offers excellent strength and elongation.

4Antibacterial and antiviral bio film technology

Antibacterial biofilm technology that suppresses the activity of microorganisms by means of
resistance to the invasion of microorganisms such as viruses and bacteria, as well as various fungi

5Eco-friendly single material film

As a single-material film for air cell packaging that has high rigidity and prevents breakage,
it is a film that applies a single material, PE, instead of using conventional nylon and PET, which present difficulties with recycling.
The single-material film is an eco-friendly film material with high strength, heat sealing, and gas barrier properties;
it is easy to process and offers additional benefits such as process stability and ease of recycling.
