Modern retractable bags come in two main types – zippers and adhesive tapes. The choice of closure is a matter of taste. Some people say a bag with tape is easier to use. Others say zippers help better protect held items. This article describes the features you can find for bags of both types.
The first aspect to consider is the type of bag material. The most commonly used kinds of plastics are polyethylene (MDPE, HDPE, and LDPE), and vinyl. Plastic is too inadequate to preserve things, but reusable bags composed of this element are very light.
LDPE polyethylene can protect stuck items from dust, marks, and humidity. MDPE further protects them from tears and punctures. HDPE protects you from all of that and more. However, if you want maximum protection, you can consider a tough vinyl bag. These all kind of bags are considered the best child-resistant packaging materials and do not harm children in any way.

The next aspect is the color. The color can vary across the spectrum, from black and white to pink and blue. Another factor to consider is opacity, which ranges from crystal clear to completely opaque. It is important to note that the opacity of the material comes with its durability. The transparent film is used for display, while the opaque film is used to hide or protect objects that are blocked from the sun.
They can also be specially printed with a gift message or advertising copy. Modern printing technology allows the use of 1 to 7 colors. Footprints can only be on one side or on both sides of the element. If you want to have a personalized print on your bag, you can consider the overall color scheme.
