  • Formulation for achievement of oil and grease resistance and release paper properties
    Patent number: 7019054
    Abstract: A formulation, and a process for making same, is disclosed which is useful as a coating or treatment for imparting oil and grease resistance to an underlying substrate. The formulation does not contain any fluorochemicals. At the same time, however, the formulation provides oil and grease resistance properties that are equivalent to known coatings and treatments which contain fluorochemicals, particularly those coatings which are permitted to come into direct contact with food products. Therefore, the formulation of the present invention is ideal for use as a coating for paper and paperboard, including paper packaging such as that utilized in food wrappers, food containers, food receptacles and the like, and for other shaped articles. The formulation is also useful as a coating or treatment for providing release properties to an underlying substrate without the use of silicone.
    Type: Grant

  • Wrapper for smoking article, smoking article, and method of making same
    Patent number: 5121759
    Abstract: A wrapper for a smoking article which, when wrapped about a tobacco column, provides improved sidestream smoke reduction, improved ash formation, and acceptable mainstream smoke taste and sidestream smoke odor subjectives. These objectives are attained by forming a single cellulosic sheet containing a filler comprising basic magnesium carbonate and, where desired, a co-filler of calcium carbonate. In addition, the sheet may be treated with a burning chemical such as alkali metal salts of organic carboxylic acids, and compatible acids.

  • Cigarette paper with reduced CO on burning
    Patent number: 4590955
    Abstract: The present invention relates to smoking article wrappers having a non-ionic surfactant added to the wrapper. The non-ionic surfactant is added to the wrapper in an amount sufficient to reduce the amount of carbon monoxide produced upon burning of the wrapper.
