What to care about in selecting zipper

Intro: Pick! Pull! Push!


It feels so comforting to enjoy the pushing process on the condition that the zipper is fluent.

When selecting zippers, our first move tends to be pushing the puller to test if the zipper is fluent. We take fluency into consideration as a priority.


Specific to the luggage zipper, we pay attention to the durability at the same time.

It’s like a universal consensus we always fill in the case more than its official capacity, no matter which luggage size we buy.


An overloaded case requires high standards for zippers’ durability. In the store, we normally try to use a pen to stab through the zipper chain.


If stay complete, we are convinced the zipper is strong enough to hold our overload stuff. If not, I’m afraid we’d better prepare an additional luggage strap.


So to choose a convenient zipper, what to care about? Before answering this question, we need to dig deeper inside the zipper.

Structure of zippers

Broadly speaking, we are inclined to divide the zipper into two parts: the puller and elements, which are also what we are familiar with.



To achieve our intended results, we normally add modifications to the puller and elements.

 

What to choose:

  • Metal Puller

The most frequently applied zipper has to be metal zippers, which are cheap and easy to present logos.

 
  • Rubber / Silicone Zipper Puller

In general, it is quite hard to distinguish between rubber and silicone zippers.


Only when you touch them in person can you differentiate them separately.


The most difference lies in the price. Normally, silicone zippers are more expensive. That's for its high stability, little color absorption, and environmental friendliness.


The high stability allows the puller to survive its quality under extreme situations, such as high temperatures.


Another important advantage is its little color absorption. Imagine the dark fabric equipped with white pullers. The regular rubber puller has a potential risk of being stained with black dots.


Silicone is also known as a rather environmental-friendly material to be used in production.

 
  • PU Puller

PU puller features in its high compatibility with various kinds of bags, such as backpacks, waist bags, lunch bags, and laptop bags.


Its exterior shape can be sewn as you wish. Traditional styles are as follows.

 
  • Injection Zipper Puller

This kind of puller features in its puller tab. As the picture shows, the puller is equipped with a cylindrical object.

 
  • Mixed Puller

A mixed puller, as its name implies, consists of two different materials. For example, the following zipper comes from an English brand VERAGE.


The puller is made of plastic and metal at the same time, which makes the puller looks much more elegant.

 

  • Double Coil Zipper

Here we welcome the famous zipper designer - YKK. It's like a milestone in the zipper industry. Multiple zippers come from their specialists.


One of them is the "RCW" zipper. The most unique design lies in its double-element structure.



8RCW(DOUBLE COIL)


“RCW" is a zipper with a double racquet coil chain. The racquet coil was designed for bags and backpacks, where resistance to abrasion is required.


The double-element structure more than doubled the chain's resistance to puncture compared to the usual zipper.


It prevents the chain from being easily punctured with pens and other similar objects.


To be noticed, the YKK zipper is way more expensive than other zippers. If required, we can provide local zippers for contrast.

 
  • Reverse Zipper

It's easy to distinguish between the reverse zipper and the regular zipper.


If the front side of the zipper along with its teeth, slider, and puller are completely visible, then that is a regular coil zipper.


If the coil on the same zipper is shown on the reverse side with the slider working on the flatter side of the zipper, then that is a reverse coil zipper (a variation of the coil zipper).


The stitching on the reverse coil zipper can be seen on the front side and its slider allows a wide range of pullers.


Reverse coil zippers can be used for water-resistant or waterproof functionalities with PVC or rubber coating involved.



Since the reverse zipper can be "invisible", here we discover a backpack- a completely water-resistant version.


We add a cover layer to cover the zipper inside. With a combination of the water-resistant zipper, cover, and exterior surface, the whole bag reaches to high-security level.


The high water resistance makes it suitable for the containment of valuable properties, such as cameras, watches, and laptops.

 

Conclusion

Zippers play a crucial and indispensable role in the luggage part. Its function decides the capacity and convenience of the case.


Multiple choices of zippers are available for us. The selection process means a lot.


Choose based on the case's capacity and special requirements.
