As a recyclable packaging material, plastic is unmatched in durability, design versatility and re-usability. Sierra’s plastic boxes outperform standard corrugated cardboard boxes and provide better long-term solutions to organizing and storage:

• LIGHT-WEIGHT CONSTRUCTION -- lighter than traditional materials such as corrugated cardboard, wood, acrylic, glass, or tin
• 
  
• CLIMATIC CHANGE -- resistant to temperature changes from 5º to 212º F (-15º to 100º C)
• 
  
• STACKING STRENGTH -- can withstand up to 600 lbs of pressure; more durable than a standard corrugated box and three times the strength
• 
  
• RECYCLABLE AND REUSABLE -- acid-free 100% recyclable environmental-friendly plastic
• 
  
• MAINTENANCE-FREE -- maintenance free durability, can be easily sanitized and maintains near new appearance for years
• 
  
• MATERIALS -- made of copolymers of polypropylene and pigments; extrusion manufactured; constant alveolar lamination in a single piece (fluted)
• 
  
• ABOUT POLYPROPYLENE -- polypropylene has the lowest density of the resins used in packaging; it is strong and resistant to chemicals; and since it has a high melting-point it can be utilized in applications requiring that a container be filled with a hot liquid
