Constructed from a robust 3-mil thick polyethylene formulation, the Ultrasac Heavy Duty Contractor Bags are engineered to withstand the rigorous demands of construction sites and commercial environments. Each bag measures 32.75 by 47 inches, offering a generous 42-gallon capacity suitable for bulky debris, mixed construction waste, and heavy industrial refuse. The material composition prioritizes puncture and tear resistance, ensuring the bags maintain structural integrity when loaded with sharp materials such as broken drywall, metal scraps, or wooden offcuts. The inclusion of integrated ties in each pack provides a convenient closure method, allowing for secure sealing of contents without additional fasteners.

Functionally, these bags deliver reliable containment for both wet and dry waste, with a design that minimizes leakage and odor migration during temporary storage. The black coloration not only conceals unsightly waste but also offers basic UV resistance for short-term outdoor use. The heavy-duty construction supports consistent performance across various applications, from remodeling projects and demolition cleanups to industrial janitorial tasks. The 50-count pack offers extended usage between replenishments, making it a practical choice for high-volume operations. The formulation of the polyethylene blend optimizes flexibility and strength balance, preventing brittleness at lower temperatures while maintaining stiffness for easy handling. The bags feature a flat bottom for stable stand-up filling and a consistent wall thickness that reduces the risk of stress fractures at seams. Designed for compatibility with standard 42-gallon trash cans and carts, they also function effectively as liners for larger roll-off containers or direct drop-in bins at job sites. Texture-wise, the bags exhibit a smooth exterior with a slight matte finish, reducing friction when sliding across rough surfaces. The material thickness provides a sturdy feel during lifting and carrying, supporting loads without excessive stretching or deformation. Users in construction, landscaping, and facility maintenance will find these bags suitable for mixed debris, including dirt, concrete dust, packaging materials, and general construction waste. The ties are integrated into the top hem, allowing for quick access and secure knotting when the bag is full. The core advantage of this bulk pack lies in its cost-effectiveness and performance consistency. The 3-mil thickness meets common heavy-duty specifications, offering a strong alternative to standard consumer-grade bags. The commercial orientation ensures compliance with typical worksite durability requirements, reducing the frequency of bag failures and associated cleanup time. While not intended for hazardous materials, these bags provide reliable service for general heavy waste disposal in demanding environments, making them a staple for contractors and facility managers who prioritize reliability under load.
