Various sleeves and bags or packaging goods, especially floral groupings such as bouquets and pot plants, can be provided using the present invention. Exemplary sleeves are manufactured with an outer wall and an inner wall, each of which is formed of two layers. The outer layers are a transparent or semitransparent sheet material such as polypropylene, and the inner layers are a nonwoven fabric material made of a compatible polymer. The outer and inner layers of each wall may be printed with complementary images or patterns. The inner and outer layers of the one or both walls may be fastened to each other not only along the side edges of the sleeve, but also at discrete locations along the top edge where the sleeve is opened. The connection can be made using glue or the equivalent, by melting or welding the two layers together, or by punching a tab of the outer layer through the inner layer. The top and bottom edges of the inner and outer layers may be coincident, or not. The top and bottom edges of the inner and outer layers may form a single straight line, plural connected straight lines (zigzags), or curved lines. The bottom edge of the sleeve may be sealed or opened, and it may include a gusset. The fabric inner layers may include chemical treatment to preserve or protect the product contained within the sleeve.
