PET explained

 

APET, rPET and Bio-PET are 100% recyclable and are collected by UK kerbside household rubbish collections.   PET is a recyclable and reusable plastic which can be Super-cleaned to create a multi-use plastic from both post-consumer waste and post-industrial waste.

 

Charpak’s PET packaging contains a minimum of 50% PCW (post consumer waste) and up to 40% post industrial waste.

 

Charpak’s waste is returned to re-processors to be Super-cleaned and re-processed to create plastic sheet for reuse in new packaging.

 

99.8% of Charpak’s rPET contains food grade recycled plastics.

 

Clear rPET is widely recycled

 

Our Bio-PET is produced of a waste product from sugar cane that is converted to Ethanol to form the basis of a standard PET product. This means no fossil fuels are used to produce it. This product can be recycled straight back into standard PET.

APET Amorphous Polyethylene Terephthalate

 

APET, is a type of PET and one of the best clear plastic materials for thermoformed packaging.

 

APET is a highly shiny and transparent clear plastic packaging whose optimum use is on shelf display and visual merchandising in retail.

 

APET is best used for automotive, manufacturing solutions, DIY and household, transport and distribution, electronics, beauty and cosmetics, and luxury gift packaging (non-food).

RPET retail ready packaging

rPET Recycled Polyethylene Terephthalate

 

rPET is super clean recycled food grade APET.

 

All Charpak’s rPET has full FDA/FSA food approval.

 

rPET has high transparency and perfect for visual merchandising on shelf in retail, with the added advantage of increasing shelf-life of perishable (and non-perishable) products.

 

rPET uses a high percentage of post-consumer waste* with an ABA layer of Food Grade material which conforms with UK / EU approved food packaging regulations.

 

There are two methods of manufacturing rPET, both of which give rPET its certified food contact assurance:

 

  • 10% outer layers (5% each layer) are made from Virgin APET, with the inner layer manufactured from a minimum of 50% post-consumer waste*. Virgin rPET is therefore the only plastic which comes into contact with food products.

 

  • A minimum of 50% post-consumer waste and up to 40% post-industrial waste is ‘super-cleaned’ and added to Virgin APET.

 

rPET is best used for cheese and dairy packaging, ambient food, food-to-go, confectionery, cakes and desserts on-shelf packaging.

CPET Crystalline Polyethylene Terephthalate

 

CPET is a PET generally used in microwaveable and ovenable packaging.

 

This is not available in Clear and will usually be produced in black and other colours.

 

Charpak can supply a standard version and also a NIR Black version (Near Infra-red detectable).

 

The NIR version is detectable by Material Recovery Facilities (MRF’s) and so is more readily recyclable.

 

CPET, as a type of PET is partially crystallised during the production process. This process gives CPET an opaque finish. This partially crystalline structure provides a stronger, more durable, plastic than rPET. CPET provides a highly effective protective barrier against oxygen, water, carbon dioxide and nitrogen.

 

Products manufactured from CPET are suitable for temperature range of -40°C to +220°C.

 

CPET is best recommended for conventional freezer proof, ovenable and/or microwaveable products.

PETG Polyethylene Terephthalate Glycol

 

PETG is also a type of PET with an addition of glycol. The addition of Glycol removes the hazing effect seen during the heating of PET and prevents the undesirable crystallisation effect which causes standard PET to become brittle.

 

Products manufactured from PETG are clearer and more shock resistant; in addition to being easier to weld in the manufacturing sealing process.

 

PETG is supplied crystal clear or can be supplied with ‘Medical’ Blue Tint.

 

Gamma Radiation Sterilisation is used by the medical industry for plastics. Gamma rays pass through the plastic at relatively low temperatures, thoroughly sterilising the plastic.

 

The different types of PET have varying degrees of tolerance to the radiation and PETG is more stable allowing the products to be irradiated within the packaging.

Black rPET Polyethylene Terephthalate 

 

Black rPET contains 50% post-consumer waste and up to 40% post-industrial waste.

 

Charpak operates a closed-loop system to ensure black rPET waste goes back into our packaging products.

 

Black rPET whilst recyclable, is not widely recycled in the current UK waste infrastructure.  Alternative solutions to this challenge are recommended by Charpak.  For more information please visit the FAQs section.

 

Products manufactured from black rPET include bases for cheese selection packaging, chocolate packaging and premium dessert packaging.

Coloured PET Polyethylene Terephthalate 

 

Coloured PET will nearly always be the basis of the post-consumer waste in black rPET.

 

Coloured PET is used for a variety of packaging products.  Examples of coloured packaging include gold, silver and bronze packaging, which is recyclable because it does not contain metal.  These coloured plastics are manufactured specifically for the food industry, with a gloss and shiny finish, approved for food contact. 

 

Charpak can match all colour pantone references to a client’s brand.  Minimum order quantities are required.
