Plastics : maximizing container space for plastic film rolls

Here's a detailed but simple guide on maximizing container space for plastic rolls:

Container Loading Strategy:

Roll Positioning:

• Vertical vs. horizontal loading
• "Eye to sky" vs. "eye to wall"
• Mixed loading patterns
• Weight distribution
• Stability concerns

"Eye to sky" vs "eye to wall" refers to how cylindrical rolls (like paper or plastic film) are positioned in containers or storage

"Eye to sky" the roll stands vertical and core points up/down like a can standing up. It is better for heavy rolls, and is characterized by its stable stacking, favors less roll damage and uses limited floor space.
"Eye to wall" the roll lies horizontal, its core points sideways, like a can lying down. It is better for lighter rolls and is characterized by height restrictions, favors easy unloading and can use multiple layers.

Space Optimization:

Standard 20ft Container:

• Maximum rolls vertically
• Stack lighter rolls on top
• Use corner spaces
• Consider roll diameters
• Account for door clearance

Standard 40ft Container:

• Multiple row options
• Mixed diameter planning
• Length optimization
• Weight distribution
• Height maximization

Safety Considerations:

Securing Methods:

• Proper dunnage
• Strapping methods
• Air bags for gaps
• Corner protection
• Anti-slip mats

Dunnage is material used to protect, secure, and stabilize cargo during transport and storage. It includes air bags, wood blocks, foam pieces, ...

Weight Limits:

• Container max weight
• Floor load limits
• Stack height limits
• Weight distribution
• Balance points

Loading Tips:

Practical Methods:

• Pre-plan loading diagram
• Heaviest rolls bottom
• Fill all gaps
• Protect roll edges
• Secure each layer

Common Sizes:

• 20ft: 5-6 rolls across
• 40ft: 10-12 rolls across
• Height: 2-3 rolls typically
• Consider door opening
• Allow handling space

Documentation:

• Loading diagrams
• Weight calculations
• Photos of loading
• Container condition
• Securing methods

Best Practices:

• Calculate before loading
• Consider roll sizes
• Plan for safety
• Document everything
• Regular crew training
