Kasseja

Kasseja is the plural form of the Finnish noun kassi, a bag or sack used to carry items. The term is commonly used for bags employed in shopping, travel, and everyday errands.

Kasseja vary in size, material, and design, including fabric tote bags, paper bags, and plastic bags. Common materials are cotton or other textiles, paper, and various plastics; some kasseja are reusable and washable, while others are intended for single use.

In everyday practice, kasseja are a central part of consumer activity in Finland and many other countries. Reusable kasseja are promoted as a way to reduce waste and fossil-fuel use, while single-use plastic kasseja have faced restrictions, fees, or bans in many regions.

Care and durability depend on the material: textile kasseja can be washed and reused many times, while paper bags are typically used for lighter loads and may degrade when wet; plastic bags vary in strength and reuse potential.

Kasseja intersect with retail, packaging, and sustainability, reflecting consumer behavior and policy choices around waste management.
