Packaging material for food and beverage products and daily supplies with durability, heat and pressure resistance, transparency and excellent recyclability.

Since Samyang's PET bottles are widely recognized for their unique qualities of non-toxicity, transparency, preservation, and resistance to pharmaceuticals, they are increasingly being used as a substitute for glass and aluminium cans both domestically and internationally. In particular, PET bottles have been identified as excellent food containers that are free from environmental hormone issues.

Characteristics

  • Harmless
    to human body

    The PET Bottle, approved
    by the FDA for perfect non-toxicity, is a sanitary container that has passed various standard sanitary tests and is also safe from environmental hormones.

  • Use of materials that enable long-term preservation

    Compared to other plastic containers, the volume of oxygen, carbon dioxide, and water vapor can be extremely low, so they can be stored for several months or more without any deterioration of the contents.

  • Stability with low risk
    in case of breakage

    After filling it with content,
    it boasts excellent safety that does not break even if dropped from a height of 2 meters and does not generate fragments even when forcedly damaged
    by a physical external force.

  • Designed containers
    with beautiful appearance

    It is much clearer than glass bottles and other plastics, allowing the contents to stand out.

  • Easy to handle due
    to the lightweighting.

    Since it weighs only one-thirteenth to one-fifteenth of a glass bottle, handling it is easy and logistics costs are saved.

  • Eco-friendly containers
    that are easy to recycle

    Clean containers that can be completely combusted and do not generate harmful substances such as dioxins.

Products

  • Heat Resistant Bottle PET bottles that hold high-temperature (86~91℃) contents.

    The neck section is crystallized, and there is a panel along the body to prevent the deformation of the bottle. It is mainly used as a container for drinks which need to be pasteurized at high temperatures, such as fruit drinks, ionic drinks for sports, and pressure-resistant coffee bottles.

    Charging Temperature
    Fill at high temperature (86~91℃)
    Neck
    crystallized
    Body Type
    Panel type to prevent negative pressure deformation
    Content
    Perishable products that require high-temperature pasteurization.
    Application case
    Juice, sports drink(ion drink), etc.
  • Pressure Resistant Bottle PET bottles for soft drinks containing carbon dioxide gas

    Pressure-resistant bottles are usually filled with 4 volumes of CO2 and, subsequently,
    the bottles' volume expands, and shapes are deformed easily as the external temperature rises. To prevent this, a streamlined body was created, and a "Foot" converging to the center was added on the bottom.

    Charging Temperature
    Fill at room temperature (20~24℃)
    Neck
    Non-crystallized
    Body Type
    Streamlined or smooth curved shapes to prevent carbonation from deforming
    Content
    Carbonated beverages that require CO2 replenishment
    Application case
    Coke, Cider, etc.
  • Heat & Pressure Resistant Bottle PET bottles for low-carbonated beverages
    that require post-sterilization (65℃) treatment.

    These bottles have excellent functionalities due to possessing both pressure resistance and heat resistance.

    Charging Temperature
    Post-sterilization after filling at room temperature (65℃)
    Neck
    Crystallized
    Body Type
    Streamlined or smooth curved shape to prevent the loss of carbonation
    Content
    Products containing perishable fruit juice and milk with low carbonated drinks
    Application case
    Oil-based carbonic acid, fruit juice carbonic acid, etc.
  • Normal Pressure Bottle PET bottles that hold contents at a normal pressure and temperature.

    Food containing bottles, such as spring water, soy sauce, and vinegar, and alcoholic beverage containers, such as Soju and Takju, etc. are involved.

    Charging Temperature
    Filled at room temperature (20~24℃)
    Neck
    Non-crystallized
    Body Type
    Ring style to prevent negative pressure deformation
    Content
    Non-perishable products
    Application case
    Spring water, Soy sauce, Vinegar, Soju, Takju, etc.

Production
Process

  1. 01 Solid-State Polymerization

    A process that gives the resin a viscosity that is proper for elongation.

  2. 02 Injection

    A process of producing a basic form (i.e., Preform) that is proper for elongation.

  3. 03 Elongation

    The process of completing the bottle by blowing high-pressure air into the mold after heating the injected preform to make it easier to stretch.
