PET blow-molded bottle

PET blow-molded bottle for premium cosmetics packaging

PET blow-molded bottles are produced from polyethylene terephthalate (PET) material using mature blow-molding processes, offering a balance of good clarity, rigidity, and lightweight characteristics.

Description

PET material offers good barrier properties and surface gloss, making it suitable for applications such as beverages, food, daily chemical products, and pharmaceuticals that require both visual presentation and packaging safety.

Core selling points of PET blow-molded bottles:

  1. Excellent clarity and displayability: PET has high optical transmittance, accurately presenting the color and texture of contents and enhancing shelf display.
  2. Good strength and rigidity: Compared with some flexible plastics, PET provides better structural strength and dimensional stability, suitable for packaging designs that need to be self-supporting or load-bearing.
  3. Good barrier and sealing performance: Provides a certain barrier against water vapor and common gases; combined with appropriate closures, it can safeguard the quality of the contents.
  4. Recyclable and widely available: PET is a common recyclable material with mature recycling systems in most regions.
  5. Customizable production: Capacity, neck specifications (diameter and thread), color, surface treatment, and printing can all be customized to customer requirements, supporting sample validation and small-batch trial production.

Suggested technical parameters:

  1. Material: PET (Polyethylene Terephthalate); material grade and additives to be confirmed per customer requirements.
  2. Typical capacities: 30 mL to 2 L (custom sizes available).
  3. Wall thickness and tolerances: Set according to product strength and hand-feel requirements; common range 0.4 mm to 2.0 mm (depending on container size and application).
  4. Neck specifications: Common 18/410, 20/410, 24/410, 28/400, etc. (customized to match closures and caps).
  5. Temperature reference: Typical operating temperature range approximately -20°C to +60°C. Short-term hot fill or thermal filling should be specified and validated in the contract.
  6. Surface treatments: Screen printing, thermal transfer printing, labeling, shrink sleeves, matte/gloss finishes, etc. Scratch-resistant or anti-static treatments available on request.

Applicable scenarios for PET blow-molded bottles:

  1. Beverages and food: mineral water, juices, condiments, ready-to-drink nutritional liquids, etc. (confirm food-contact compliance).
  2. Daily chemicals and personal care: bottled shampoos, conditioners, body washes, hand soaps, etc.
  3. Pharmaceuticals and laboratory reagents: containers for reagents or solutions not intended for high-temperature sterilization (confirm per regulations and customer requirements).
  4. Industrial and household cleaning products: cleaners, solvents (confirm chemical compatibility).
  5. Promotional and gift packaging: strong surface decoration suitability makes PET ideal for high-end packaging that enhances brand presentation.
