When choosing packaging for dairy products, the key factors are a comparison of operating costs and the physical and chemical properties of the material. Dairy packaging made of PET or glass meets modern standards, with each option offering specific technological tolerances and usage capabilities.
Glass packaging: characteristics and impact on the product
Glass is a traditional solution for milk packaging that has remained popular and in demand for decades. This popularity is due to the material’s characteristics:
- ✅ Chemical inertness and safety. Glass does not interact with the product and does not affect its composition, taste, or properties.
- ✅ Rigidity. The material cannot be accidentally punctured or cut.
- ✅ Aesthetics and perception. Glass packaging looks premium and visually appealing.
However, glass packaging for dairy products also has disadvantages. The first is environmental impact: glass production requires high energy consumption, increasing the carbon footprint. The second is fragility. Glass requires careful handling during filling, loading, transportation, and unloading, which increases operational costs. Finally, weight is another factor. Glass containers are heavy, leading to higher logistics expenses.
PET packaging: features for dairy products
Plastic containers are actively gaining market share and are currently the most popular solution. The reason is simple — PET milk packaging is practical. This is reflected in the following properties:
- ✅ Lightweight. Minimal packaging weight reduces logistics costs.
- ✅ Durability. PET containers do not break when mishandled and do not crack.
- ✅ Hygiene. Plastic is not subject to degradation from natural environmental factors.
- ✅ Barrier properties. PET provides reliable protection against external influences.
- ✅ Wide range of form factors. PET bottle preforms are available in various volumes, designs, and colors, with different neck standards.
In addition, plastic packaging is more affordable. This makes PET containers a cost-effective solution for businesses.
When to use PET and when to use glass
There is no single correct answer. A comparative analysis of PET and glass shows that both materials have properties suitable for dairy packaging. However, when selecting a specific type of container, it is also important to consider the distribution radius and the manufacturer’s brand positioning.
Glass packaging is relevant for the “Premium” and “Organic” segments. It is suitable for brands that are not focused on high sales volumes, emphasize maximum barrier properties, and plan to reuse containers.
PET is a more budget-friendly option, ideal when production efficiency and reduced logistics and storage costs are priorities. This type of packaging is suitable for large-volume filling and is recommended for manufacturers targeting the mass market.
Myths and facts about PET and glass in the dairy industry
There is still a belief that plastic is unsuitable for the food industry and negatively affects product taste and properties. In fact, this is a myth. PET packaging for beverages does not affect the product when high-quality raw materials are used, standards and technologies are followed, and proper temperature conditions are maintained.
The second misconception concerns food packaging safety. Glass is often considered unmatched in terms of hygiene and environmental friendliness. However, when sanitary processing rules are followed and certified raw materials are used for plastic container production, PET packaging also meets strict food safety standards. Moreover, PET is now successfully recycled and suitable for reuse. Considering its practicality and affordability, it can be confidently stated that there is no more convenient and cost-effective alternative to PET packaging.
Packaging selection recommendations
The modern market offers several solutions when choosing a material for dairy products. Ultimately, the decision comes down to balancing aesthetics and practicality. In most cases, PET packaging prevails as a more cost-effective and practical option. However, quality remains crucial, and packaging should be sourced from a reliable manufacturer.
