It can be confusing which product to buy, especially for the 1st time buyer. Here?s a quick reference to make sure you know exactly what you?re getting when you buy this Collector Protector Album Sleeve. Sleeves come in varying materials and thicknesses. BOPP Poly bags are shiny and extremely clear. They are more stiff/rigid thus they hold their shape and are less prone to wrinkling or fingernail dents than softer material such as CPP, LDPE, HDPE or polyethylene. They are less pliable than the softer bags which means they will split at the seams easier. However, careful handling will prevent most of these splits. They will hold their clarity longer than other poly bags which tend to become more milky or yellow over time. Don?t be confused between transparent and translucent. Our bags are transparent. They provide a better barrier to outside elements than the PE bags.Overall, if you want to make your covers look the best they can, while providing great protection, you?ll be happy with this product. Thanks for your interest in our sleeve. We are happy with it, and hope you will be too.
