Instructions for Attaching a Shrink Band to a Bottle

The Importance of Shrink Bands

Shrink bands, also known as heat bands, serve as a highly effective method for maintaining the security of your packaged items. They create a tamper-proof seal, giving consumers confidence in the safety and quality of what they purchase. Additionally, shrink bands can be tailored with branding and product details, enhancing the overall professionalism and consistency of your packaging design.

Steps to Apply Your Shink Bands

After you obtain the shrink bands you want, proceed with these instructions to attach them to your bottles or jars:

1. Pick the Correct Size: Opt for a shrink band that closely matches the diameter of the neck of your jar or bottle. Make sure it is tall enough to cover both the cap and a portion of the container beneath it. 

2. Adjust the Shrink Band: Carefully place the shrink band on top of the cap, making sure it is aligned properly and fully envelops the closure. The band should sit uniformly around the container's rim, free from any wrinkles or folds.

3. Apply Heat:

Utilizing a Heat Gun: To begin, all you require is a compact heat gun, such as this one. Follow these instructions:
a. Adjust the heat gun to a low or medium setting.
b. Position the heat gun approximately 6-8 inches away from the container.
c. Gently maneuver the heat gun around the shrink band, ensuring that the heat is evenly distributed. If necessary, rotate the bottle to achieve consistent shrinking. Be cautious not to focus the heat on one area for too long, as this may cause the band to curl.
d. You will notice the shrink band gradually tightening around the top and cap of the container.

Operating a Heat Tunnel:

a. Set the heat tunnel to the temperature advised by the manufacturer.
b. Insert the container that has the shrink band into the heat tunnel.
c. Let the containers travel through the tunnel, where they will experience uniform shrinkage of the band due to the heat.

4. Examine the Seal: Once heat has been applied, take a moment to assess the shrink band for a snug and secure fit around both the container and its cap. The band ought to appear smooth without any wrinkles.

5. Let it Cool: Give the bottle a few moments to cool down. As it does, the shrink band will continue to tighten slightly, ensuring a robust seal.

6. Conduct Quality Assurance: Carry out a final inspection to confirm that the shrink band has been correctly placed. Look for any gaps, bubbles, or uneven sections. An effectively applied shrink band should be flawless and create a tamper-evident seal.;

Adhering to these guidelines will enable you to successfully use shrink bands on your glass bottles and jars. This process not only safeguards your products but also improves the visual appeal of the packaging, thereby boosting customer trust in your brand.
