PET DIE-CUT LIDS

INTRODUCTION​
Pre-cut plastic lids made of PET are a popular alternative to aluminium lids. The print quality achievable is higher because the plastic surface is white allowing improved graphic quality and colour definition. When transparent or clear PET with a heat-seal lacquer is used, the consumer can easily visualise the packaged product making it a highly versatile material. Metallised polyester (MET-PET) gives the lid a metallic surface and improved barrier properties.
​PET lids are less costly to transport, they travel better and do not tear when peeled. Their high puncture resistance reduces the risk of leakers and product return. Plastic die-cut lids also allow the use of "end of line" metal detection, vital in food production and testing.

A list of some of the most common PET lid material we offer can be found below.

Q-LID V 

Q-Lid V is a peelable heat-seal film that has been designed specifically for pre-cut lid use within the food and cosmetics sector. It can be manufactured with an anti-static coating to reduce de-nesting issues where the lids stick together.
It seals extremely well to PS, PP, PET, PE, PE lined paper and aluminium forming a strong, smooth peelable bond. It will also seal to PVC and is suitable for being placed in a microwave oven, convention all oven and refrigerated.
Q-Lid V has strong resistance to alcohol, vinegar and is capable of sealing through contaminated pots containing vegetable oils due to its hot-tack characteristics.
DESCRIPION:
  • 50μm PET with heat seal lacquer
  • Sealable to PS, PP, PE, R-PET, A-PET, C-PET, PE Board, PVC, PLA cups and bottles
  • Microwavable, boilable and ovenable
  • Available with print primer or slip lacquer
  • High mechanical resistance against puncturing and tearing
  • Resistant to solvents, acids & vegetable oils

APPLICATION:
Yoghurt, cream, cheese, deserts, salads, ready meals, instant soups, snacks, etc.

​Q-Lid 75PET/50HT

Q-Lid 75/50 HT is a special laminate of 75μm PET to a special grade of 50μm CPP. This laminate is formulated to have a very strong peel seal to PP and HDPE containers. This material is steamable, pasteurisable and sterilisable. This laminate will absorb significant abuse from production processes yet will seal through contamination.
​DESCRIPION:
  • 75μm PET and 50μm CPP laminate
  • Peel sealable to PP & HDPE
  • Excellent moisture, gas and aroma barrier
  • Strong mechanical resistance against puncturing and tearing
  • Resistant to solvents, oils, acids and foods. It can be pasteurised and retorted. The peel seal is maintained after these processes.

​APPLICATION:
Yoghurt, cream, cheese, desserts, salads, ready meals, sterilised or pasteurised products, etc.

Q-LID COMBI

Q-Lid Combi seals to PP, PE, and PS Cups. It is exterior lacquered with a printing primer for improved ink adhesion. This foil is used as lidding foil for blow-moulded or injection moulded cups and containers. It provides a sterile closure in an aseptic filling process. The film is a medium peel and is tamper evident. 
Q-Lid Combi can be used in applications that require hot-fill to 50°C and protects well against humidity and micro-organism attack. Optimum seal depends on sealing pressure, time, temperature and container type. 
DESCRIPION:
  • 50μm PET with heat seal lacquer
  • Good moisture, gas and aroma barrier
  • Good mechanical resistance against puncturing and tearing
​
APPLICATION:
Yoghurt, cream, cheese, desserts, fruit juices, snacks, instant soup, salads, etc.

Q-Lid PET CO-EX

INTRODUCTION​
Q-Lid Co-Ex lids has a layer of extruded polypropylene that heat-seals to PE & PP containers. Since extrusion coated materials do not use solvents in the heat-seal layer, they can be considered more environmentally friendly than heat-seal lacquered material.
A key advantage of Co-Ex is that they seal within a broad temperature range and do not require as precise temperature control of the heat-seal heads. Seal strengths achieved are extremely strong, a valuable attribute where the finished product may travel at altitude before reaching the consumer. 
Where a product requires a long shelf life or is pasteurised or sterilized, Co-Ex PET lids are an ideal solution. Other advantages include the elimination of container warping or panelling when packing hot-fill products. 

​PET lids with a thick layer of extruded polypropylene lacquer are used for sealing cups containing products which, due to their life cycle, must be pasteurised. Alternatively Q-Lid Co-Ex PET lids are used in situations where an extremely strong seal is required or where the packaged product has a high fat content or contains spices. 
Q-Lid Co-Ex has been designed specifically for general purpose use. It seals extremely well to PP, PE, PE lined paper and aluminium forming a strong, smooth peelable bond. It will also seal to glass, PS and PVC and is chillable and ovenable. Q-Lid 50 PET Co-ex has strong resistance to the effects of freezing and is capable of sealing through contaminated pots containing vegetable oils due to its hot-tack characteristics. The printed side is treated with co-polyester for outstanding ink adhesion.
DESCRIPTION:
  • PET thickness: 50μm
  • Co-Ex coating thickness: 15 - 40gsm
  • Sealable to PP & PE substrates
  • Resistant to pasteurization and sterilization
  • Microwavable, boilable and ovenable
  • Designed for hot-filled products
  • Resistant to solvents, acids & vegetable oils

APPLICATION:
Pates, pet food, canned food, spices, sauces, etc.
