Product description & requirements
Personal care products include a wide variety of products used in personal hygiene and embellishment. These products are not regulated by legislation but are commonly referred to as cosmetics (which need to conform to specific regulations). A cosmetic is a preparation designed to be used on any part of the human body including the mouth, to modify the odours, its appearance, to cleanse it, to keep it in good condition, to perfume it or to protect it.
Cosmetics range from everyday hygiene products such as soap, shampoo, deodorant, and toothpaste to luxury beauty items including perfumes and makeup and does not include products regulated as therapeutic goods. Legislation for cosmetics varies from country to country. Cosmetics and personal care products are made from industrial chemicals which may be synthetic or natural occurring chemicals.
The target was to design standout PET containers to capture the attention of the consumer, keeping in mind final performances and ease in handling. Containers could be transparent allowing to see the content or opaque/colored. Targets are also packaging optimization plus lightweighting and restyling of “old” bottle shapes.
Development & challenges
PET results to be chemically compatible with most ingredients for cosmetics. Considering the use of colorants in cosmetics which may be sensible to UV light, better would be to opt for clear containers containing UV barrier additive. Challenges were to create asymmetrical or oval shaped bottles; a customized bottle with logo, special texture or particular neck-finishes (compatible with existing closure) are other challenges. Flat areas are preferable to glue label or graphic contents.

Results & Packaging Features
Some of the most important features of this kind of packaging are: color, shape, symbol, words, touch/feeling. These characteristics are important also during purchasing, so new and fresh designs are needed, linked to good performance, mechanical resistance and thoughness.

ECS SP 50 and ECS SP 80 : new SIPA single-stage PET bottle production systems
This range of ISBM machine is designed for production of small lots of special containers, with features that enable quick change-overs between different product configurations. The machine is also characterized by a compact lay-out and high energy efficiency.
Low energy consumption
EXAMPLE ON A ECS SP 50
Energy consumption: 18.5 kWh (Including machine + hot runner + PET loader)
Container weight: 7.8 g
Cycle Time: 11 sec
The ECS SP 50 and 80 are ideal for production of bottles with volumes as small as 20, 30 and 50 ml, typically used for such products as pharmaceuticals and also shampoos and lotions used by hotels. For production of bottles of this size, the machine accepts molds with as many as 16 cavities, enabling outputs of up to 6000 bottles/hr. It can also mold larger bottles, up to 10 L, using two- cavity molds.
- PC user friendly
- Very low power consumption for machine, hot runner and PET loader,low carbon footprint and costs
- Proportional valve controls for injection clamp press open/close movement
- Servo motors for: screw rotation, index rotation, blow mold clamp open/close movement
- Energy recovery of servo motors during breaking: highly innovative and efficient solution
- Small hydraulic oil reservoir: reduction in energy consumption
- Hydraulic circuit and components positioned in the lower side of the machine, guaranteeing a clean production environment, ideal for food and pharma applications.
