Plastic materials

The composition of CGL Pack's products

CGL Pack is a thermoforming specialist and its partnership with Faerch Plast places us in a position of materials expert. We prefer the use of recyclable or mono-materials to improve the environmental footprint of the packaging solutions we offer our customers for the marketing of their products. All the materials we use entirely conform to the strict European legislation in force. We equally concentrate, within our R&D department, on the use of materials possessing particular characteristics such as sealability, resistance to heat and cold etc.

CGL Pack uses extruders to process APET, PS and PP. Faerch Plast is a CPET specialist and offers a very broad product range in that material.

The main materials currently employed by the Group for the manufacture of plastic packaging possess the following characteristics:

APET: amorphous polyethylene terephthalate

APET is a material characterized by extreme transparency, solidity and resistance to shock. Tests equally prove that it performs very well with regard to internal pressures and stress-cracking and provides an excellent barrier for gases, ultraviolet radiation and water. It can be used at temperatures ranging from -40°C to +70°C.

Lids, salad trays and other packs requiring visual highlighting of the product have every interest to be designed using APET.

APET can also be broken down into CPET for foods that need to be heated int he microwave or traditional oven (see below).


RPET: recycled polyethylene terephthalate

The acquisition of 4PET in the Neitherlands in August 2018 positions us as the leader in industrial scale recycling. Indeed, we are able to recover, sort, wash post-consumer household packaging types bottles and food trays and turn them into new packaging. This system is possible in loop which makes the RPET a very ecological material. Transformation cycles are endless without danger to food security. To date we put in our packaging a minimum of 50% of RPET and for some packaging solutions we can go up to 100%. Choosing the RPET for your applications is a responsible choice and you contribute to an ecological balance close to zero when you use this material.

PET transparent pack

CPET (crystalline polyethylene terephthalate)

Primarily used for prepared foods, CPET is made from APET and can contain up to 100% recycled content. This material is suitable for temperatures from -40 ° C to + 220 ° making it ideal for oven and microwave or food products that need to be frozen. CPET offers very good sealing properties and high barrier properties.


CPET tray


These are materials made especially in our factories; they are designed to facilitate the sealing of thermoformed trays even in difficult conditions. These solutions are ideal for fresh meat and fish. PET-based mono-materials Clearseal® or MAPET II are ecological alternatives to complex packaging solutions (a mixture of multi layers materials) because they disrupt recycling channels while our mono-materials are very easily recyclable. they benefit in addition to the recyclability bonus that are part of the extension of the sorting instructions. The MAPET II is made from recycled materials (50% guaranteed, 80% effective on average and soon 100% possibility) and recyclable in the post-consumer plastic waste stream (bottles, trays).

Sealable pack

PP: polypropylene

Polypropylene is translucid to opaque and very resistant. Depending on the type of PP, it can resist temperatures of about -6°C to 125°C, so is suitable for freezing as well as for microwave heating. It is often employed for food packaging given its resistance to temperature and grease and its smooth and brilliant appearance.

CGL Pack possesses an extruder dedicated to manufacturing this material.


PS: polystyrene

Basic polystyrene, called PS "crystal" for its transparent appearance, is a hard and brittle material, which can be colored. Its mechanical and thermal properties can be modified by the addition of plasticizers to make it a "shock" polystyrene. It is a very easy material to transform and often used for the manufacture of packaging intended for the healthcare and medical markets. CGL Pack has an extrusion line dedicated to the manufacturing of this material.
