Benefits of technology

[0007] The present invention provides an infusion beverage package having a good balance of properties including, being biodegradable, good tensile strength and a short sink times, while being transparent enough so as to enable a user of the package to see the contained infusion beverage precursor within the package before infusing the package into water. The infusion beverage package of the present invention is prepared from a porous web derived from a biodegradable thermoplastic polymer, wherein the package has a transparency of at least about 30%, a tensile strength of at least about 2N/15 mm, and an

Problems solved by technology

However, with the current infusion beverage packages, the customer is unable to see the specialty beverage precursor due to the translucent nature of the current packages available and is unable to appreciate t

[0079] Bicomponent spunbond samples were prepared using the process described in U.S. Pat. No. 5,382,400 which is hereby incorporated. The bicomponent spunbond has a sheath / core configuration and contains as the sheath component, a polyactide available from Cargill Dow, LLC under the designation Ingeo™ 6350 D. The core component is a polyactide available from Cargill Dow, LLC under the designation Ingeo™ 6250 D. The ratio of the sheath component to the core component is 1:1 in each of the Examples below.

[0080] The fibers were prepared by extruding about 0.7 grams per hole / min of the total polymer at a temperature of about 410°-430° F. (210°-221° C.) and the resulting fibers were quenched with air. The fibers were drawn at a FDU pressure of 12 psi. The fibers were laid down on a forming wire moving at about 135 feet per minute (41.2 meters per minute). The fibers had a denier of about 3 dpf (3.3 dtex). The fibers deposited on the forming wire were preliminarily bonded with a hot air...

Abstract

The present invention provides an infusion beverage package having a good balance of properties including, being biodegradable, good tensile strength and a short infusion times, while being transparent enough so as to enable a user of the package to see the contained infusion beverage precursor within the package before infusing the package into water. The infusion beverage package of the present invention is prepared from a porous web derived from a biodegradable thermoplastic polymer, wherein the package has a transparency of at least about 30%, a tensile strength of at least about 2N/15 mm, and an infusion time of less than about 20 seconds. In addition, the seal strength of the package is at least 2N/15 mm.

Description

FIELD OF THE INVENTION [0001] The present invention relates to a porous infusion beverage package, which holds an infusion beverage precursor material. BACKGROUND OF THE INVENTION [0002] Infusion beverage packages are known in the art and typically contain a beverage precursor material, such as tea or coffee. To produce a beverage, the package containing the beverage precursor is typically infused into hot water, by placing the package into hot water, pouring hot water onto or through the package, or heating water to desired temperature while the package is immersed in the water. Alternatively, the beverage infusion package may be placed in cold water to form the beverage. [0003] These packages are generally in the form of a pouch, a bag or a sachet and are generally prepared from a very thin and light weight paper product. Typically, these packages are translucent when wet, and the contents of the package can only be seen after the package has been infused or while the package is i...
