Posted by Creative Boxes on May 2nd, 2024

Pinch lock mylar bags, also known as pinch n slide or pinch n pull bags, are a popular choice for packaging a variety of products in the UK. These innovative bags offer a unique combination of benefits, making them ideal for businesses and individuals alike. This guide delves into everything you need to know about pinch lock mylar bags, from their features and uses to where to buy them in the UK.

What are pinch-lock Mylar Bags?

Pinch lock mylar bags are constructed from metallised polyester, commonly referred to as mylar. This material offers several advantages, including:

  • Durability: Mylar is highly puncture and tear-resistant, ensuring your products are protected during storage and transportation.
  • Barrier Protection: Mylar acts as a barrier against light, moisture, and oxygen, which can extend the shelf life of your products and prevent spoilage.
  • Odour Control: Mylar bags are excellent at containing odours, making them ideal for storing food items, teas, coffees, and other fragrant products.

The defining characteristic of pinch-lock mylar bags is their reclosable opening mechanism. Unlike traditional ziplock bags, these bags feature a special closure system that requires pinching the sides and pulling them apart to open. This mechanism offers several advantages:

  • Child Resistance: Pinch lock closures are certified child-resistant, making them ideal for packaging products that could be harmful to young children, such as medications or supplements.
  • Tamper Evident: The closure can be heat-sealed for tamper evidence, providing peace of mind that your products haven't been tampered with after packaging.
  • Ease of Use: Despite the child-resistant feature, pinch lock closures are easy for adults to open, requiring minimal effort.

Uses for Pinch Lock Mylar Bags in the UK

Pinch lock mylar bags have a wide range of applications in the UK market. Here are some of the most common uses:

  • Food Storage: Mylar's barrier properties make it ideal for storing dry food items like coffee beans, loose-leaf tea, herbs, spices, and baking ingredients. They help maintain freshness and prevent flavour loss.
  • Medical and Pharmaceutical: The child-resistant and tamper-evident features make pinch-lock mylar bags perfect for packaging medications, supplements, and other medical products.
  • Electronics and Hardware: These bags offer protection from moisture and static discharge, making them suitable for storing electronic components, circuit boards, and small hardware items.
  • Collectibles and Artwork: Mylar's light-blocking properties help protect light-sensitive collectables like photographs, comics, and artwork from fading.
  • Product Protection: Mylar's durability and barrier properties safeguard your products from damage, spoilage, and contamination.
  • Extended Shelf Life: By limiting light, moisture, and oxygen exposure, pinch-lock mylar bags can significantly extend the shelf life of your products.
  • Discretion and Odour Control: The opaque nature of mylar bags keeps contents hidden from view and effectively traps odours within the bag.
  • Child Resistance and Tamper Evidence: These features provide peace of mind for products that require extra security.
