Hi All,
As promised, a look at another Biotec patent.
Biotec own a patent for "Multiple layer foil partially composed of starch", and the first thing that I thought of was crisp/snack bags.
Seems to be another huge market .... "The snack food industry in the
UK is currently in a phase of expansion
with annual sales of 8 billion packets of crisps and 1 billion packets of peanuts. This portion of the snack food market is worth over 1 billion per year with forecasts predicting a doubling of this value by the end of the century. Currently sales are increasing at a rate of 4% per annum for crisps and 6.2% per annum for savoury snacks"

========================
From a case study on snacks ....
Snacks, which are integrated into the work, relaxation, and recreation of mericans, supply about 25% of our daily calories. In fact,
North Americans are the largest per capita consumers of chip snacks, comprising over 36% of the world market.
Feeding our demand for snacks is the $72 billion snack food and wholesale bakery industry. This industry generally includes wholesale bakery goods that generate 40.2% of sales, specialty snacks 12.9%, confectionery products 21.9%, and salty snacks 25%. Included in the salty snack category are meat snacks and pork rinds, salted nuts and peanuts, and the snack chip industry.
The $13 billion snack chip industry provides consumers with potato chips, potato crisps, corn chips, tortilla chips, pretzels, ready to eat popcorn and extruded cheese products such as curls, balls, and puffs.
Americans are increasing their consumption of snack foods. During the past decade, dollar sales of salty snacks have increased an average of 5.2% while sales in pounds have increased 3.2%. According to U.S. Industry & Trade Outlook '99, market growth for salty snacks is projected to increase by 2 to 4% over next five years.
Table 1: Sales of chip snacks: 1998
Type of chip
In millions GBP
Potato chips 1,517.3
Tortilla chips 1,354.5
Corn chips 239.8
Table 1 shows the sales of chip snacks for 1998. The other category includes potato crisps. Crisps are baked and some are made from reconstituted potatoes. The largest crisp brand is Proctor and Gamble's Pringles, in addition, Frito-Lay has several baked brands.
The largest snack chip manufacturer is the Pepsico Inc. Their snack foods division,
Frito-Lay, has over a 60% market share, sales of $7.474 billion, and the top selling brand in each of the major snack chip categories except ready-to-eat popcorn. Frito-Lay has achieved its success through extremely effective marketing, production and distribution as well as very aggressive competitive strategies.

Abstract of correspondent: CH680590
A single or multiple layer foil with an essentially reduced gas permeability has at least one layer composed at least in part of an essentially thermoplastic starch. In order to obtain a single or multiple layer foil which is at least almost completely insensitive to humidity, the one layer has at least one additional hydrophobic polymer, such as a polyolefine, which is mixed with the starch during the production of the one layer, and/or the starch is at least partially cross-linked at the surface of the one layer and/or the one layer is covered with at least one other layer which is at least almost completely insensitive to humidity.
