Even with something as simple as sheet protectors, there are several points you should consider when buying them. Keepfiling wants to make it easy for you to choose the right sheet protector. Follow this guide to learn about Keepfiling sheet protectors and it will help you pick the type of sheet protectors you need.
The truth is that a some manufactures and dealers sell polypropylene sheet protectors under the pre-text that they are HEAVY WEIGHT when they in reality upon receiving the ordered sheet protectors or page protectors the shopper find what they got was a thinner gauge more like a STANDARD WEIGHT sheet protectors or less.
Now there does not exist a "higher council" for determination of weight definition for sheet protectors or pages protectors. However with the following we have set a standard based upon many years of experience working in this field at a professional level. We can only emphasize to look for or request the material gauge from your supplier before you make your purchase.
If material gauge is not displayed one easy way to compare is to look at the actual shipping weight per 100 pages. It should NOT be less than what has been written below:
There are advantages for both type of clarity. However often it falls to personal preferences but here are a few points why you may prefer one type over the other.
The most clear of the two textures. Preferred when photos or color printed materials are to be displayed. Colors are shown more vibrant and rich in glass clear pages.
The disadvantage is that the clear surface of the material will reflect light easier from surrounding light sources which can make it a bit uneasy to read through in the long run. In addition, finger print marks are easier shown on this type of material but of course can be easily cleaned off.
This material type is often also called low reflective. Back in time non-glare was more frosted in the surface but eventually it has evolved into today's type of material which in comparison is a bit more dusty. Most major brand names use this type of material today. At Keepfiling we prefer the term low reflective as these pages are more suitable for written material and, black and white print.
The inserted documents are displayed as a bit more dusty compared to the glass clear material. It is this 'dustiness' that makes the low reflective surface easier for reading as it is less straining for the eyes because less light is reflected of the surface compared to glass clear material. Finger print marks and scratches from daily usage are not as obvious on the non-glare material.
Keepfiling offers the letter size (8-1/2 x 11) sheet protectors in the above two material types. They can be found here:
We've attempted to take several pictures to show you the differences between the types of sheet protectors. On the left we have glass clear material sheet protectors, and on the right we have non-glare (low reflective).
Please note that it is difficult to show on screen the real clarity of the two materials, so only take these photos as a reference to how they might look in person, and also note that all documents were printed on copy paper with an inkjet printer.
Material ThicknessThe thickness of the material also plays a small part in the clarity of the sheet protectors. Technically speaking, the thicker the material means that less light will be able to penetrate through and therefore the result is a more dull view. However, most users will not be able to tell the difference in clarity between the different thickness of sheet protectors.
Despite what we have said, there is no right or wrong to which clarity you should be using for your documents. At the end of the day, if comes down to personal preferences. Some customers may prefer the non-glare material because they think the 'dusty/murky' texture reflects less light and will be easier for the eyes to read. On the other hand, some customers may not like it because it's not clear and will think it's not 'crisp' enough for the document it's holder, therefore they will prefer the glass clear material.
The reason why these materials are considered archival safe is because they do not contain plasticizers. Plasticizers are added to plastics to increase their flexibility and durability but the downside is it emits hydrochloric acids when the plastic deteriorates. This is not safe because over time, it's inevitable that there will be some deterioration to the sheet protectors you are using. If they contain plasticizers, the deterioration will cause hydrochloric acids to be released and this can severely damage your documents. PVC contains plasticizers and there are sheet protectors on the market that are made from PVC. These sheet protectors are therefore not archival safe. Using them will cause damage to your documents over time, for example, colors on photographs might be damaged or text from printed documents will stick to the plastic destroying your papers completely.
The images below shows exactly how PVC sheet protectors can damage both the document and the sheet protector itself. As you can see the ink is ruined on the document and is stuck onto the sheet protector making a mark. This can be a disaster if you've decided to use non-archival safe sheet protector as your documents could be ruined and will be very hard to restore.
Avoid storing things like photos and and other memorable items that you wish to keep for a very long time.
