Liners come in three resin types: Linear Low Density, High Density and Higher Alpha Olefin. Which type is best for you depends on your application, but there are a few general points to consider.

Linear Low Density - LLDPE	High Density - HMW-HDPE	Super Hexene - HAO
These are everyday-use liners that suit virtually any application and environment. The most commonly used bag in the industry Equal or better strength than a conventional Linear Low Density bag at a lower gauge Good puncture and tear resistance Optimum stretch in the transverse (TD) and machine (MD) directions Film is quieter and smoother than high density USDA- and FDA-approved resins	Great all-purpose, cost effective liners, these bags are suitable for heavy, wet and non-sharp objects. Stronger than linear low density liners of the same gauge due to higher tensile strength and great load-bearing capacity Great puncture resistance, but less tear resistance than linear low density Can handle extreme temperature changes without compromising material integrity Better chemical resistance Effective odor confinement when properly sealed Require 2/3 less petroleum-based raw material so they cost less to ship and store USDA- and FDA-approved materials	The best features of High Density and Linear Low Density bags in one. Ideal for heavy, irregular waste, and best used when maximum stretch and puncture resistance are needed. Latest generation resin with a proprietary formula Gauge-for-gauge up to 50 percent stronger than comparable Linear Low Density bags Maximum puncture and better tear resistance Handles medium to large loads Suitable for heavy, irregular waste Safest choice when you are uncertain about what kind of refuse you'll have Require 2/3 less petroleum-based raw material so they cost less to ship and store USDA- and FDA-approved resins
