Description
Custom Antistatic Bags at Hudson Poly Bag
Hudson Poly Bag, as a custom poly bag manufacturer, extrudes, prints and converts antistatic LDPE and HDPE. We make both the standard pink antistatic bags as well as clear antistatic materials, depending on customer specification. We deliver on time, on spec and on price. We simply do what we say that we will do.
The Technical Details of Antistatic Materials
There are three major classes of internal, migratory antistatic agents: esters, amines and amides. The esters are not widely used because the antistatic properties are typically of short duration. Amines can be used for non-electronic end uses, but they can react with polycarbonate, which is a typical component of printed circuit boards. Hudson Poly bag uses only amine-free amides to circumvent this issue.
All three migratory agents utilize the same method of creating the antistatic properties, they migrate to the surface and absorb the humidity in the air. When this has been accomplished, it is not unusual to notice a slight slippery or greasy feeling on the polymeric material.
There has to be a conditioning or bloom time for the surface of the material to become antistatic. Typically, for LDPE or LLDPE poly bags, this is two days. For polymer structures such as HDPE or PP poly bags, this takes considerably longer. Film that is wound under tension is also much slower, until it is unwound and can gain exposure to the humidity in the air.
The antistatic properties are typically measured in two ways, decay rate and surface resistivity. The decay rate is a measure of the time required (seconds) to dissipate a certain fraction (90%) of an applied 5000 volts charge. Surface resistivity is the resistance of a product at its surface measured in ohms. A product is said to be antistatic if the surface resistivity is 109 (read 10 to the 9th power) to 1013 ohms.
