Abstract
A multilayer flexible packaging material comprising cyclic olefin copolymer in the flowable formulation-contacting layer (“inner layer”) does not induce significant scalping of flowable formulations comprising essential oils such as eucalyptol, menthol, methyl salicylate and thymol in the presence of limonene.
Claims21
A packaged flowable formulation comprising:
- a) flexible package having a perimeter comprising
- i) a first multilayer flexible film component comprising:
- A) an inner layer comprising one or more cyclic olefin copolymers;
- and
- B) at least one additional polymeric layer;
- and
- ii) a second multilayer flexible film component comprising:
- A) an inner layer comprising one or more cyclic olefin copolymers;
- and
- B) at least one additional polymeric layer;
- and
- iii) a heat seal disposed along at least a portion of the perimeter of the flexible package;
- wherein the second multilayer flexible film component is disposed in facing relation to the first multilayer flexible film component with the inner layer of the first multilayer flexible film component is disposed in facing relation to the inner layer of the second multilayer flexible film component and the first and second multilayer flexible film components and the heat seal define a reservoir;
- and
- b) a flowable formulation disposed in the reservoir, the flowable formulation comprising a solvent and limonene.
A packaged liquid formulation comprising:
- a) flexible package having a perimeter comprising
- i) a first multilayer flexible film component comprising:
- A) an inner layer comprising one or more cyclic olefin copolymers;
- and
- B) at least one additional polymeric layer;
- and
- ii) a second multilayer flexible film component comprising:
- A) an inner layer comprising one or more cyclic olefin copolymers;
- and
- B) at least one additional polymeric layer;
- and
- iii) a heat seal disposed along at least a portion of the perimeter of the flexible package;
- wherein the second multilayer flexible film component is disposed in facing relation to the first multilayer flexible film component with the inner layer of the first multilayer flexible film component is disposed in facing relation to the inner layer of the second multilayer flexible film component and the first and second multilayer flexible film components and the heat seal define a reservoir;
- and
- b) a liquid disposed in the reservoir, the liquid comprising water, between about 1 and about 35% w/w alcohol, and at least one essential oil.
A method of reducing scalping of a flowable formulation contained in a reservoir defined by packaging material comprising the step of interposing an inner cyclic olefin copolymer layer between the flowable formulation and additional layers of the packaging material.
