In industry, the bottling of beverages, household chemicals, and technical formulations requires careful selection of packaging. It is important that it can withstand logistics loads and maintain the stability of the product formula. In addition, packaging for liquids determines not only the shelf life of the product but also the efficiency of automated filling lines. They are available in a wide range, but polymer containers are in high and stable demand in the B2B sector. Using such packaging combines 3 important business properties – practicality, durability, and economic feasibility.

In industry, the bottling of beverages, household chemicals, and technical formulations requires careful selection of packaging. It is important that it can withstand logistics loads and maintain the stability of the product formula.

They are available in a wide range, but polymer containers are in high and stable demand in the B2B sector. Using such packaging combines 3 important business properties – practicality, durability, and economic feasibility.
Main requirements for liquid packaging
When bottling liquid products, whether beverages, technical solutions, or cosmetics, great attention is paid to the choice of containers. They must meet several requirements:
- ✅ airtightness to prevent leaks;
- ✅ high resistance to impacts and damage;
- ✅ durability – containers must provide suitable conditions for storing contents for a long period;
- ✅ resistance to temperature changes and UV;
- ✅ chemical inertness with respect to active ingredients in the products: pigments, oils, acids, alkalis;
- ✅ compliance with hygiene and environmental standards.
Another important factor is the stability of the container’s geometry and conformity of the neck to current closure system standards, making it easier to select PET caps for packaging. Liquid packaging that meets all these requirements can improve the efficiency of production with automated bottling lines.
Types of liquid packaging
Depending on the product's purpose and storage conditions, different containers are used. Packaging for liquid industries includes rigid and flexible solutions, each with its own operational and recycling features. Among common types of packaging:
Glass packaging
A traditional type of container with almost absolute gas impermeability. Glass is an inert material that does not affect the organoleptic properties of the contents. It is durable, suitable for multiple uses, environmentally friendly, and hygienic.
However, glass packaging has drawbacks – significant weight and fragility require careful handling, increasing logistics costs and production defect risks. Such containers are more often used in the premium segment of alcoholic beverages or for specific pharmaceutical products.
Flexible packaging
These are doypacks. They are convenient for sauces or technical concentrates. Flexible packaging is more affordable, does not break when dropped, and is lightweight. However, bottling food products and technical liquids requires complex specialized filling equipment. Also, this packaging has less resistance to vertical loads during storage.
PET bottles and jars
Plastic packaging for liquid products is currently the most demanded and widespread option. PET jars and bottles are used in various industries: food products, household chemicals, technical formulations. Polymer containers not only meet current packaging requirements but also have several important advantages:
- ✅ lightweight;
- ✅ resistance to internal pressure, allowing carbonated beverages to be filled;
- ✅ reliability and durability;
- ✅ wide choice of neck standards;
- ✅ possibility of manufacturing in different form factors.
Such packaging can be produced directly at the factories, adapted to the product volume. For this, PET preforms for bottles are used, which can be ordered from us.
The company «Zavod Preform» manufactures blanks for plastic containers of various volumes, colors, and neck standards. Preforms can be ordered in bulk with regular deliveries across the country. The assortment also includes caps and handles for plastic bottles. Each client is provided with an individual approach and convenient business solutions.
