Abstract
The invention discloses a preparation method of bamboo fiber paper cups. The invention relates to a bamboo fiber paper cup and a production process thereof. The bamboo fiber paper cup mainly structurally comprises a hollow fiber cup body, and is characterized in that the cup body comprises an outer layer, an inner layer, a hollow layer arranged between the outer layer and the inner layer and a coating layer above the inner layer. The outer layer and the inner layer are prepared from the following components in parts by weight: bleached bamboo fibers, dahurian larch fibers, modified starch, chitosan, talc powder, a dispersant, guar gum, glyceride hydrolase and a wet-strength agent. The hollow layer is prepared from the following components in parts by weight: polypropylene hollow short fiber pulp, dahurian larch fibers, chitosan, talc powder and a dispersant. According to the above settings, the outer layer and the inner layer are produced by employing bamboo fibers. The bamboo fiber pulp not only is environment-friendly, but also has the characteristics of being excellent in antibacterial property, bacteriostatic and free of peculiar smells. The hollow fiber layer has the functionsof being light in weight, heat insulative and warm-keeping. The bamboo fiber paper cup serving as a hot drink paper cup and a cold drink paper cup simultaneously is relatively safe.
Description
technical field [0001] The invention belongs to the field of paper cups, and in particular relates to a preparation method of bamboo fiber paper cups. Background technique [0002] Disposable paper cups can be seen everywhere in life, and they can be thrown away after use, which is hygienic and convenient. However, there are endless safety disputes about whether it contains carcinogens, whether it can hold hot drinks, and whether it can be used repeatedly. There are roughly three types of disposable paper cups on the market: one is made of white cardboard, which is mainly used to hold dry food such as popcorn and fried chicken, and cannot hold water; the second is waxed paper cups, which have a layer on the inner wall Paraffin wax is used for waterproofing, and can be used to hold frozen drinks, carbonated drinks, etc., but the temperature of the container should not exceed 40 degrees Celsius; the other is the "paper-plastic cup", which is a layer of paper on the outer wall...
