68% Sand
12% Soda Ash
10% Limestone

recycled glass used at levels as high as 90% when available

time and place identification

coating material applied to outside surface of glass containers

surface lines

-preserves container strength
-facilitates flow through glass manufacturers' line and customer's filling line

Pristine (new) bottle= 40k-50k
moderate abrasions= 10k-20k
deep scratch= approx. 5k
cracks = 1k- 1.5k

-any force applied to the container that cause the glass to stretch, compress, bend, or twist
-increases in load=increase in deformation

low cofefficient of friction (glass to glass)
-organic (cold end) surface coating: stearate, oleric acid, polyethylene

ability to withstand abrasions (glass to glass)
-combination of organic (cold end) and inorganic (hot end) coatings

-applied when container is about 1k F
-results in a permanent coating of tin oxide
-provides bonding sites for the cold end coating
-imparts durability to scratch resistance
-enhances label adhesion

Monobutyltintrichloride
-also known as

-applied when container is about 250 F
-provides lubricity when dry

-improves durability of scratch resistance, both wet and dry
-preserves container strength
-Best durability-hot end and polyethylene (toughness in physical abuse, permanence, water resistant)
-critical to container light weighting

-product type
-Reusability
-filling line conditions
-labeling machines and adhesives

the reduction of the amount of glass used to make any given bottle or jar while meeting requirements for the package.

-reduces energy costs
-reduces freight costs
-reduces raw materials usage
-increases production speeds
-increases filling line efficiency
-reduces CO2

1. Blow and Blow
2. Press and Blow
3. Narrow Neck Press and Blow

dependent on uniformity of temperature in gob and molds.
-somewhat variable
-more glass required to maintain minimum thickness

Positive displacement by plunger
-less variable
-better control of glass placement
-more efficient use of glass
Limited to wide mouth finishes
-38mm and larger

Positive displacement by plunger
-less variable
-better control of glass placement
-more efficient use of glass
Limited to narrow neck finishes
-38mm and smaller

-redesign container shape, with less surface area
-remove abrupt features in surface
-redistribute glass
-change finish on container

-reduces glass wall thickness
-removed the traditional punt indentation
Success/ Savings:
-annual glass reduced by 2,100 tons
-decreased supply chain greenhouse gases by 14%
-reduced glass weight 14%
-reduced cost on a 10% avg

Static load
-boiler formula and thickness

S=(P x D)/ 2T

Dynamic load
-mass, velocity, and stiffness
-intensitivity to weight

-package design
-customer preferences
-consumer preferences
-global marketplace
-coating technology
