We provide added convenience with the ability to access items inside a bag multiple times. Many reclosable bags feature some type of zipper closure to assist with keeping the bag secure. There are different types of zipper bags designed for specific applications. Here are the types of zipper bags you might see when shopping for your supplies.
String Zipper Bags
String zipper bags provide your most basic plastic bag closure. These zipper bags provide a low-cost way to add the convenience of a reclosable zipper to poly packaging. They are typically compatible with most bagging equipment.
Because these zipper bags required less raw materials to make, they are faster to produce, which allows for quick turn arounds on bag orders. This is a no-flange type of zipper closure. String zipper bags are best used with lightweight to medium weight products.
Flange Zipper Bags
Flange zipper bags use interlocking sections to create a sealed bag. The noticeable texture felt between the zipper bags can help reassure customers that they have successfully closed the bag. Double-flange zipper bags provide excellent closure strength and help trap small particles inside, allowing these types of bags to hold a wide variety of items.
Ribbed Zipper Bags
Ribbed zipper bags are essentially the same as flange zipper bags, except the plastic material has ribs formed into it for extra grip and strength. These types of zipper bags are compatible with multiple bag styles, and they perform well at lower sealing temperatures, which helps reduce film distortion. The ribbed design allows faster production speeds on form, fill, and seal equipment, as well as pouch machines.
Double Zipper Bags
Double zipper bags provide excellent sealing capabilities while still offering an easy to use bag for customers. The two zipper tracks will most likely feature flange zipper bags with interlocking sections that create a tight seal. The double zipper design provides peace of mind that the interior contents are secure. A textured feel helps reassure customers that the bag is closed.
Tamper-Proof Zipper Bags
Tamper-proof bags often feature a tear strip that must be removed before the zipper closure can be opened. This prevents anyone from getting into the bag during shipping and allows for customer peace of mind upon arrival for consumables. Tamper-proof bags help prevent spillage during impacts that may cause a zipper to open by force. Common applications for these zipper bags include bagging pet foods, coffee, or packaged meats.
Slider Zipper Bags
Slider-style zipper bags are perfect for small or medium sized bags that will hold light to medium weight items. They are easier to open compared to your standard press and close zipper bags, especially in applications involving gloved hands. There are many types of sliders available, including ones with an hourglass shape to improve someone’s grip as they move the slider across the bag.
Particle Plow Sliders
Particle plow sliders are designed specifically for applications involving small crumbs or granulated products. The zipper itself is designed to push smaller particles out of the zipper track as the bag is closed to keep the seal secure. These types of bags are excellent for confectionary applications or other food service industries.
Mini sliders are essentially the exact same as normal sliders, except they are smaller in size and require less material to make. This allows them to be more cost-effective for applications involving lightweight products. They function the same way normal sliders do but are simply smaller in size. They are good for applications of small lightweight products that must be packaged with gloved hands.
You can purchase bags that already include a specific type of zipper, or you can purchase zipper bags separately and convert bags into your desired product with help from a manufacturing or converting company. This would be the ideal solution for someone who is creating a completely custom bag for a particular application.
