The Difference in Clarity between Polypropylene & Polyethylene Bags

What are the major differences between polypropylene and polyethylene bags? And which one offers the greater amount of clarity? In the sections below, we’ll hope to answer these questions (and more) as we unlock the physical characteristics behind each type of bag.

About Polyethylene Bags

Polyethylene bags are inert, and their translucent nature allows them to create a lower, overall static charge than polypropylene. Not to dwell too much onto the scientific aspect of this bag type, but it is important to note that according to chemists, polyethylene bags are “inert” in the sense that they won’t attract other chemical compounds (like mildews, molds, or other unwanted discolorations).

Due to the very nature of this bag, items inside will not become damaged easily, which is one of the main reasons for purchasing them. Polyethylene also prohibit a larger amount of light than their counterpart, which is good because excessive light can cause damage to collectables or items that you are trying to preserve.

About Polypropylene Bags

One of the drawbacks of polypropylene ziplock bags is that they emit higher charges. As a result, they will attract much more dirt, dust, and debris than normal. These types of bags are durable in the sense that they can help protect the items inside, and most are quite pliable as well. Unfortunately, as these bag types get exposed to the elements, they tend to become hardened and stiff.

Which Bags Offer More Clarity?

Now that we’ve broken down the characteristics associated with both bags, let’s answer the question we came to find out: which bags offer more clarity? Although it’s a close race, the clarity of polypropylene ziplock bags is higher. These bags are intended for use when you are trying to achieve high clarity in a bag, similar to the clarity of cellophane.
