What are the Performance Advantages of Self-sealing Bags

1. Sealing Performance

Zipper bags have excellent sealing capabilities, effectively preserving items and preventing food from being damaged by moisture. This significantly extends the shelf life of food products.

2. Ease of Use

Zipper bags are cleverly designed to achieve a tight seal without the need for any additional tools. Simply fold the opening of the bag and press it shut to easily complete the sealing process, making them extremely convenient to use.

3. Reusable

Zipper bags offer the convenience of repeated sealing. For unfinished snacks or food items, simply reseal the bag to effectively block out moisture, keeping the food fresh and maintaining its original flavor and texture.

4. Good for Display

Due to their excellent shelf display effect, zipper bags are highly favored and have become an important factor in attracting consumer attention. As a result, more and more products choose this type of packaging to enhance their market appeal and competitiveness.

What Types of Zipper Bags Are There?

1. Standard Zipper Bags

Also known as paste-bone zipper, these have a 13mm width and can be set to either a closed or open default state during production. When opened, the zipper slides apart from the top, with the zipper and pull tab located on both sides. To close, press and slide the pull tab into the zipper to seal it, with the opening facing up. This zipper design is widely used for packaging snacks, and it is not limited by bag type, commonly found in stand-up pouches, three-side seal bags, and various custom-shaped bags.

2. Child-proof Zipper Bags

These have a 27mm width and feature a child-lock mechanism. The soft packaging is usually closed by default and can be customized to open. When opened, the zipper pull tab is on both sides, and closing works similarly to a standard zipper. The opening method requires holding the bag with one hand while pulling the zipper open with the other hand. These bags are commonly used for packaging pharmaceuticals, tobacco, and other products, compatible with various bag types, especially stand-up pouches and custom-shaped bags.

3. Tear-open Zipper Bags

With a 22mm wide tear-open zipper, these bags come with a tear strip. During production, the zipper is placed next to the tear strip, and after the product is inserted, the edges are sealed. When the tear strip is opened, the zipper becomes accessible without exposing the product directly. The tear strip helps to prevent damage to the top of the bag, ensuring the packaging remains intact. These bags are commonly found in coffee and pet food packaging and are widely used for various bag types, especially eight-side seal bags.

What Products Are Suitable for Zipper Bags?

1. Larger Quantity Products

For products that exceed the amount needed for a single use, such as large packages of dried fruit, nuts, etc. (typically 100-200g, or even 500-1000g for family-sized packs), zipper bags are an ideal choice. These bags allow users to easily reseal the package after opening, ensuring the remaining food stays fresh and is easy to store and use.

2. Products That Need to Stay Dry

For items like seasonings, dried mushrooms, and other air-dried ingredients that need to remain dry to prevent spoilage, zipper bags are perfect for long-term storage. They quickly reseal any remaining ingredients, effectively blocking out moisture, which helps maintain the freshness and quality of the food.

3. Products That Need Protection from Insects

Sweet products like candies and preserved fruits are prone to attracting insects like ants if the package is not resealed after opening. This can lead to contamination and affect food safety. Zipper bags offer an easy way to reseal the food, effectively preventing this issue from happening.
