Plastic water bottles
29.11.2022

Water is the basis of life on Earth. Its properties largely depend not only on the quality of the liquid itself, but also on the container in which it is poured.

Plastic water bottles are a popular choice for ease of use and transportation. Following the rules of storage, water in such a container can be stored for more than one month. In addition, provided that high-quality materials are used for the production of PET containers, the mineral composition of water does not change and it remains safe for human health.

Which plastic bottles can you store water in

To store water, you can use a plastic container marked:

  • 1 – PET (polyethylene terephthalate). The largest group. A plastic water bottle should not be heated above 25°C.

  • 5 – polypropylene. Food safe plastic. Withstands temperatures of 80-96°C. Can be used in the microwave. Recommended service life – no more than 1 year.

  • 7 – polycarbonate. Sports water bottles, baby bottles are made from it. Remember that the water temperature in such containers should not exceed 100°C. Can be washed in a dishwasher.

Design of plastic water bottles – popular trends

The desire to distinguish their product on the market and at the same time protect it from possible fakes makes manufacturers look at the usual bottles of water in a new way. The design of only the labels will not surprise anyone now. The emphasis is shifting to the shape of the plastic container.

Two styles are currently popular:

  1. Blowing complex-shaped bottles. The geometry of plastic containers combines originality and convenience. In pursuit of a unique form, it is important not to forget about the comfort of use. The water container should fit well in the hand.

  2. Production of containers with a simple shape, but with complex elements. We are talking about placing a logo, company name or trademark on the surface of the bottle by blowing. Also popular are original water bottles with curly elements – notches, grooves, constrictions, pimply inserts.

Additional elements to help you stand out from the bottled water companies – this is:

  • the presence of a handle on the neck;

  • bottle caps or caps with logo print;

  • original form of self-adhesive labels.

Production of preforms with individual characteristics

The basis of the future bottle is a plastic blank. It is necessary to take into account the wall thickness of the finished container and the load that the eggplant for water must withstand.

Forming is done by internal blowing – ISBM (injection stretch blow molding). This is a two-phase production of bottles:

  • first stage – creating a preform that visually resembles a plastic test tube. At this stage, the final appearance of the neck of the container is also determined. It will not undergo any changes;

  • second stage – heating and softening of the material, followed by blowing a full-fledged bottle of the required configurations and relief.

Length, color, neck shape and weight preforms for water bottles determine the configuration and volume of the finished product. You can choose a blank from the catalog of the "Preform Plant" or order a product according to individual parameters.

Using preforms has the following advantages:

  1. Automatic quality control at the stage of creating blanks. It includes checking the quality of the raw materials used, as well as rejecting molds with defects.

  2. Compact storage. Preforms take up 12 times less space than a bottle. This allows you to create the necessary stock of goods in the warehouse, without occupying all available space.

  3. Versatility. The plastic blank can be used to blow water bottles of various configurations.

  4. Choice of standard or multi-layer preforms, as well as blanks with barrier additives. The latter involves the inclusion of nylon or amosorb.
