How are they made?
• Caps are made via an injection molding machine – the machine is known as the “press” and the tool that makes the caps is the “mold”.

March 26, 2009 Aerosol 101 Slide 9
• Polyethylene (HDPE)• Polypropylene (PP)• Clarified Polypropylene (CPP)• Copolymers (Blended)• Styrolux/K-Resin• Non-Antistat Polypropylene (NAPP)
Materials
March 26, 2009 Aerosol 101 Slide 10
Polypropylene
1. Lightweight
2. High compressive strength (top load)
3. Scuff Resistant
4. Retains stiffness and flex
5. Clearer than PE
6. Higher anti-stat levels
Polyethylene
1. Softer material – more crack resistant
2. Does not hold it’s shape when bent
3. Cloudier
4. Faster cycle times
5. Scuffs easily

Other materials Clarified PP
Use when more clarity is needed
StyroluxBest clarity, lowest shrinkage
Non-antistat PPUse when painting, printing or metallizing

Single Shell/Double Shell
March 26, 2009 Aerosol 101 Slide 23
Why use a single shell cap?
• Will fit a larger actuator – one that is larger than the valve cup
• May use less plastic than a double shell
March 26, 2009 Aerosol 101 Slide 24
…and WHY NOT?
• Caps are more size critical with regard to fitment on the can – double shells lock onto the valve cup so are not as critical
• Top load strength is diminished because caps rests on the shoulder radius
• Do not mold as fast as double shells which will affect cycle time (cost)

Marketing Questions
• What is your customer’s business - filler, manufacturer or end product user?
• Does your customer have specific requirements for an overcap - tamper resistant, functional, spray through?
• Convenience vs. cost – large cavitation vs. small, short leadtimes, uniqueness or inventory requirements
March 26, 2009 Aerosol 101 Slide 34
More questions….
• What is your competitive edge – a unique feature, distinctive look, low cost?
• What size do you need – can size, double or single shell?
• Premium product or market driven?
