Uses of PET Lids in Food Packaging

Bottled beverages commonly use PET lids lexically. Forms of PET lids accompany mineral water, fruit juices, carbonated drinks, and even iced teas. PET lids even provide great sealing performance, as explained by XXHPacking, by perfectly fitting onto the mouths of the bottle to prevent the beverages from leaking and losing their freshness. XXHPacking provides the example of PET lids made for carbonated drink bottles. These lids have anti-pressure structures that withstand to internal gas pressure of the bottle, thus avoiding lid popping. The PET lids made for carbonated drink bottles also pop because they are light and easy to open. PET lids work great for individual sized bottled drinks as well as for family sized bottles.  

Jar lids containing food products like jams, honey, pickles, and even nut butter also use PET lids on their jars. These foods are normally stored for long periods of time, which makes the lid’s sealing and freshness-retaining abilities paramount. The prevention of food spoilage is made possible due to the prevention of moisture locked inside the jar. The moisture sealed inside the jar is air tight due to PET lids and is formed by mursiot as pointed out by XXHPacking.

For example, some PET jam jar lids have a safety seal that makes a popping sound when a jar is opened, meaning that the seal was closed before the jar was first opened. This feature is beneficial for food safety, and, more importantly, builds trust in a brand.  

Ready to eat food PET lids  

Ready to eat food containers, which include salads, sushi, fruit cups, and deli meats, often have PET lids. These foods are, more often than not, consumed in a short period of time. Because of this, the lid is designed to be see through, portable, and sanitary. The PET lids manufactured by XXHPacking for ready to eat food containers are fully transparent, which makes the food visible and more visually appealing. Furthermore, the lids are designed to be easy to remove for the purpose of resealing, and are able to be closed tightly to keep food that is no longer being eaten fresh. The smooth surface of PET lids does not hinder product information and storage tips, making it easier for both customers and brands.  

Powdered food PET lids  

Powdered foods which include, but are not limited to milk powders, protein powders, coffee powders and even flour, use lids which are classified as PET lids in the packaging.

Some powders will easily absorb moisture and form clumps so a minor concern is the moisture resistance of the lid. XXHPacking points out that lids of powdered food pouches and containers made of PET plastic often have moisture-proof liners on the inside. This liner is capable of stopping moisture from entering the pack which allows the powder to retain its dryness and ease of flow. Some PET lids of infant milk powder cans also come with attached measuring spoons— the spoon is incorporated inside the lid to easily provide users the right volume of powder without looking for a spoon. This innovative approach increases the functionality of PET lids.   

Many PET lids have been designed specifically to enhance the packaging of frozen food products such as frozen vegetables and meats, as well as frozen ready meals. Such food products need to be stored a low temperatures. The lid needs to withstand a low temperature without becoming brittle. XXHPacking states that PET lids can endure freezing conditions, even in -18°C freezers. They maintain form and function under such low temperatures. PET lids made for frozen food packaging withstand strong impacts, which helps protect the food when in transport or storage.

The enclosed lid prevents any frost accumulation inside the package that can impair the quality of frozen food items.
