In the choice of paper, we mainly consider the cost, product quality, production procedures, prepared product characteristics and use of the situation! Product features: now the most commonly used are imported tape 3M, Japan, SONY, Desa and some domestic tape because different tapes have different adhesive properties. This determines that we should consider this aspect when choosing the release paper. Cost: there is a big difference between domestic and imported release paper.
Generally speaking, the public praise of domestic release paper is not very good. For example, sometimes there will be poor surface release when glue is prepared, and the release paper and product can not be torn well. Domestic release paper is certainly cheaper than imports. As there is a relatively large price difference, the company needs to consider comprehensively.深圳離型紙廠由于氣候的關系，電子模切工業冬季宜選用剝離力偏重的離型紙，夏季宜選用剝離力偏輕的離型紙。特殊需求的膠帶，在模切過程中使用的離型紙，需與離型供應商接洽。在作深度測試、對比后方可進行生產活動，以免成品產生質量問題。涂膠廠一般均選用高涂布量的離型紙，而復合廠一般均選用中等涂布量的離型紙，若是熱復合，也需要選擇高涂布量的離型紙，水膠僅需要低涂布量的離型紙即可，中等涂布量的離型紙適合油膠及保護膜使用，高涂布量的離型紙不適合保護膜使用。生產程序：這里重點是是否要沖壓或者切割,一般涉及到沖壓或者切割時,會要求離型紙的厚度,因為低克重的離型紙在用于沖壓的時候,不易沖斷,當然,這也和底紙的易碎度有關,易碎度不好的底紙在沖壓或者切割的時候會把紙和產品撕開.達不到理想或者說想要的效果。
Due to the impact of the climates, electronic die cutting industry in winter should choose the release of heavy peeling force paper, in summer should choose the release of light peeling force paper. Special requirements of tape, in the process of die cutting to use the release paper, need to contact with the release supplier. Production activities can be carried out after in-depth testing and comparison to avoid quality problems in finished products. Glue factory generally selects the high amount of coating from type paper, and the composite factory general medium was used for the coating weight from type paper, if thermal compound, also need to choose high coating weight from type paper, glue water only need lower coating weight from type paper, medium coating weight from type paper suitable for oil glue and protective film, high coating weight from type paper is not suitable for protective film. Production process: the focus here is whether to stamping or cutting, generally involves the stamping or cutting, will demand from the thickness of the paper, because of the low gram from type paper when used for stamping, difficult thrust, of course, this also and bottom paper fragile degrees, fragile degree of bad bottom paper at the time of stamping or cutting will tear the paper and products. Do not achieve the desire effect.
Release paper can be classified by plastic release paper and non-plastic release paper. Plastic release paper, because the release agent has a certain permeability, if there is no certain barrier, the release agent will penetrate into the paper, resulting in poor curing and release agent usage (high cost) and many other adverse factors. So need to do plastic coating on paper (commonly known as film), domestic generally use polyethylene (PE) particles for film, melting index is required in about 7, domestic PE particles generally choose petrochemical 1C7A.
