What is Heavy-duty Stretch Film?
Heavy-duty stretch film is a very durable and specialized version of stretch films that is produced with increased thickness and reinforced structure. These films are designed for packaging large, heavy loads or items with sharp edges, ensuring greater protection, better load stability, and high resistance to tearing and deterioration.
Characteristics of Heavy-duty Stretch Film
High Thickness and Resistance: This stretch film is thicker than other types, typically ranging from 100 to 120 gauge (25–30 microns) or more, which provides significantly higher resistance to impact, tearing, and puncturing.
High Molecular Structure: Heavy-duty stretch film is produced with a special blend of polymers that establish an optimal balance between load retention and stretchability. Its unique molecular structure evenly maintains tensile strength and prevents load shifting during transport.
Cost Savings Over Time: While the film itself is more expensive per roll than light stretch wrap, its durability reduces losses from damaged items, shrinkage, and rewrapping.
Material Efficiency: Although they are thicker, heavy-duty films often allow fewer wraps or layers due to higher strength per unit of film. This can reduce overall material usage if properly applied.
Better Protection: Provides strong protection against mechanical damage, harsh handling, moisture, dust, and environmental wear.
Applications of Heavy-duty Stretch Film
Transportation: Standard stretch films often lack the capability to hold heavy and bulky loads, leading to tears and potential damage to the product during handling. Therefore, heavy-duty stretch films are utilized for packaging these types of pallets.
Construction Industry: In the construction industry, various materials come in different designs and shapes, which can be heavy and even have sharp edges. Therefore, it is necessary to use more resilient stretch films.
