A method for manufacturing a food and/or beverage packaging container, the method comprising the steps of:
- injection molding a preform using a two phase injection system, wherein a first phase of the two phase injection system comprises injecting a first material into the preform and a second phase of the two phase injection system comprises injecting a second material into the preform;
- disposing the preform in a mold;
- blow molding the preform into an intermediate article having a length, a diameter and side walls having a wall thickness;
- and
- trimming the intermediate article to form a finished container having a wide mouth neck.
A method for manufacturing food and/or beverage packaging containers, the method comprising the steps of:
- producing a first finished container by:
- injection molding a first preform using a two phase injection system, wherein a first phase of the two phase injection system comprises injecting a first material into the first preform and a second phase of the two phase injection system comprises injecting a second material into the first preform,
- disposing the first preform in a mold,
- blow molding the first preform into a first intermediate article having a length, a diameter and side walls having a wall thickness, and
- trimming the first intermediate article to form the first finished container and produce scrap material, the first finished container having a wide mouth neck;
- and
- producing a second finished container by:
- injecting the scrap material into a second preform,
- disposing the second preform in a mold,
- blow molding the second preform into a second intermediate article having a length, a diameter and side walls having a wall thickness, and
- trimming the second intermediate article to form the second finished container.
A method for manufacturing food and/or beverage packaging containers, the method comprising the steps of:
- producing a first finished container by:
- injection molding a first preform using a two phase injection system, wherein a first phase of the two phase injection system comprises injecting a first material into the first preform and a second phase of the two phase injection system comprises injecting a second material into the first preform,
- disposing the first preform in a mold,
- blow molding the first preform into a first intermediate article having a length, a diameter and side walls having a wall thickness, and
- trimming the first intermediate article to form the first finished container and produce scrap material, the first finished container having a wide mouth neck;
- and
- producing a second finished container by:
- injecting the scrap material into a second preform,
- disposing the second preform in a mold,
- blow molding the second preform into a second intermediate article having a length, a diameter and side walls having a wall thickness, and
- trimming the second intermediate article to form the second finished container,
- wherein the finished container comprises the first material and the scrap material comprises the second material, the scrap material being free of the first material and the finished container being free of the second material.
