PP woven bags

  Brief Overview of PP Bags and Their Manufacturing Polypropylene (PP) bags have a rich history. Invented by Giulio Natta and Karl Ziegler, this polymer became popular for its strength, flexibility, and resistance to moisture and chemicals. History of PP Bags: 1960s-1970s: First PP woven bags appeared, made by extruding polypropylene into tapes and weaving them into durable fabric. Advancements: Improvements in weaving technology enhanced strength and load-bearing capacity, making bags suitable for heavy materials like cement and fertilizers. Present Day: Widely used in agriculture, construction, and food packaging, valued for durability, lightweight, and cost-efficiency. PP woven bags are indispensable for packaging grains, seeds, fertilizers, chemicals, and animal feeds, offering excellent protection and customization options. Manufacturing Process: Extrusion: Polypropylene granules melted and extruded into tapes. Weaving: Tapes woven into strong fabric. Cutting and Printing: Fab...

Preparing Plastic ABS sheet for Painting

  Preparing Plastic ABS sheet for Painting In my on going experiments with synthetic surfaces, I recently purchased two sheets of ABS plastic for painting. ABS stands for “acrylonitrile butadiene styrene” and is a thermoplastic polymer. It has multiple uses for such things as computer cases to Legos. It can be run through a 3D printer to make all sorts of things. It can come in almost any color, but is typically available in black or white. In sheet form it often has a rough “haircell” texture on one side, and the opposite side is smooth as glass. I first heard about this material for artwork many years ago from other artists who liked painting on it. One of those people is my friend,  Kim Dow . She told me she gets it in thin sheets, and then has it glued to a foamcore for support. The two I bought are 1/8 inch thick, and 17×21 inches. The price varies online, but these were @ $10 each. The smooth side is sanded down enough to remove the shine, and make it capable to hol...
