Hudson Poly Bag is a custom manufacturer of plain and printed poly bags and poly tubing. With 7 extruders, 3 printing presses and 13 bag making machines, we can satisfy your most demanding needs, on time, on spec and on price. We simply do what we say that we will do.

LDPE (low density polyethylene) and its cousin LLDPE (linear low density polyethylene) are the workhorses of the poly bag industry. They are widely used across all markets due to its clarity, supple feel and inherent flexibility.

Hudson Poly Bag extrudes, prints and converts these materials for many, many applications. As the properties of individual bags can vary greatly with changes in mil thicknesses, bottom seal or sideweld style, or blend ratios of LDPE and LLDPE, we suggest you discuss your particular application with us first.

Advantages of LDPE Poly Bags

Good Clarity: Although not quite as clear as polypropylene, LDPE poly bags have good clarity for general purpose applications. LDPE and LLDPE resins are produced in various clarity levels, so it is a good idea to specify the clarity desired to your supplier.

Good Strength: LDPE and particularly LLDPE, have good overall strength properties without sacrificing overall clarity with increased mil thicknesses. Specialty LLDPE resins such as Octene or Hexene enhance the performance of LDPE. By sharing the intended end use of your packaging, a custom poly bag manufacturer can provide the best mix of properties to provide product success.

Good Moisture Retention Properties: As a member of the olefin family of resins, LDPE and LLDPE are good materials to keep moisture within the package or prevent moisture from migrating to the product in the package.

Disadvantages of LDPE Poly Bags

Poor Low Temperature Characteristics: LDPE used alone, is not a good choice for freezer applications. When the end product is intended to go into a freezer, the industry standard is to modify the LDPE by blending it with 3% EVA (ethyl vinyl acetate) or other blending agents to get around this inherent problem. Properly modified bags are then suitable for freezer or cold temperature applications.

Fair High Temperature Resistance: For applications at room temperature this is a non-issue. However, for microwave or steam sterilization, this is not the material of choice. LDPE starts to soften at approximately 170-180 degrees Fahrenheit, and is not suitable.
