All You Want to Know About Dry Food Packaging

Materials such as PE (Polyethylene), OPP (Oriented Polypropylene) and CPP (Cast Polypropylene) are frequently used in dry food packaging. Since these materials have different properties, the areas they are used in packaging design and their purposes may also differ.

1. PE (Polyethylene):
Polyethylene is a widely used material in the plastic packaging industry. PE is preferred due to its properties such as flexibility, durability and water resistance. The use of PE in dry food packaging is generally preferred to protect the content from external factors (moisture, air, etc.). PE can also be used as an inner lining material in various types of packaging.

2. OPP (Oriented Polypropylene):
OPP is obtained as a result of the orientation process of polypropylene material. This material is often used in printed packaging and has a glossy surface. OPP performs well in providing protection against external factors and can increase the shelf life of the product. OPP is frequently used in the packaging of products such as biscuits and crackers.

3. CPP (Caste Polypropylene):
Cast polypropylene is produced by melting polypropylene and pouring it into a mold. CPP is a material that is resistant to high temperatures and suitable for refrigerator-freezer conditions. Due to these features, it can be preferred in the packaging of frozen foods and hot products.

Each material has advantages and disadvantages. Packaging design should be made according to the characteristics of the product, storage conditions and consumer expectations. Material selection should consider factors such as preserving the freshness of the product, promoting the product effectively, and providing convenience to the user.
