maitopurkki

Maitopurkki, often translated as milk carton or milk jug, refers to a container specifically designed for the storage and distribution of milk. These containers are commonly made of coated paperboard, a material chosen for its strength, recyclability, and insulating properties. The inner surface is typically lined with a thin layer of plastic, such as polyethylene, to prevent leakage and maintain the milk's freshness. An outer layer of printing allows for branding, nutritional information, and expiration dates.

Historically, milk was delivered in glass bottles, which were heavy and prone to breakage. The introduction of the paperboard milk carton in the early 20th century revolutionized milk packaging. Early designs were often wax-coated, but advancements led to the more durable and hygienic gable-top cartons that are prevalent today. These cartons are designed for easy pouring and often feature a tamper-evident seal.

Milk cartons come in various sizes, from single-serving portions to larger family-sized containers. Their lightweight nature and stackable design also make them efficient for transportation and storage in retail environments. While paperboard is the most common material, some milk is also packaged in plastic jugs, particularly in North America. The environmental impact of both types of packaging is a subject of ongoing discussion, with efforts focused on improving recycling rates and developing more sustainable alternatives.
