Desiccant paper is a semi-rigid substance that adsorbs moisture when used in a package as per the paper's thickness. Desiccant paper consists of adsorbent particles made of silica gel or bentonite that helps in drying of a product. Desiccant paper can be cut into various shapes as per packaging requirement.
Advantages:
Desiccant packaging material must have good breathable performance, strength and excellent heat sealing. Different packaging materials can be selected according to the application industry and grammage weight. At present, the widely used desiccant packaging materials mainly include: TYVEK, ordinary non-woven fabric, spunky non-woven fabric, Japanese non-woven fabric, breathable tissue(cotton) paper, OPP film, etc.
Material introduction and application scope
1. Composite paper: Composite paper is the composite of different characteristics of materials together, with good printing and decorative effects.
Scope of application: Suitable for 1g - 10g bag desiccant.
2. Breathable cotton paper: composed of fiber and heat seal layer. Can be used for small size silica gel desiccant packaging, for packaging montmorillonite strength is not enough and easy to leak powder, good air permeability.
Scope of application: less than 5g small packaging bag desiccant
3. Ordinary non-woven fabric: it is composed of oriented or random plastic fibers, is a widely used packaging material, it has a certain strength, and excellent air permeability, but used for packaging montmorillonite, easy to leak powder;
Scope of application: 2g-200g bag desiccant.
4. Mesh paper: high strength, good dust resistance, wide applicability, higher price than ordinary composite paper, but far lower than dupont paper, is the ideal choice of high-grade packaging materials.
5.Tyvek: It is the trademark of a series of sheet products of DuPont Company.Tyvek is made of high-density polyethylene fiber. It is an ideal material for all kinds of desiccant packaging, with high strength, folding resistance, tear resistance, anti-static, good air permeability and other characteristics, but also has excellent weather resistance and chemical resistance, dust-free design, used for packaging desiccant, both good air permeability, and has enough strength and beautiful printing effect, the only disadvantage is high price.
Scope of application: Suitable for 0.5g - 1000g bag desiccant.
6 spunlaced non-woven fabric: it is the high pressure micro water jet to a layer or multilayer fiber net, so that the fibers intertwined with each other, so that the fiber net to be reinforced with a certain strength.
Scope of application: more than 100g bag desiccant.
7. Japanese non-woven fabric: also known as Japanese fiber paper, is a kind of non-woven fabric, with high temperature resistance, high mechanical strength and other characteristics, high technical requirements, high cost.
Scope of application: 1g-1000g bag desiccant.
8.OPP film: composed of PP and PE film, it is a transparent packaging material, which can easily observe the state of adsorbent in the desiccant package. OPP itself does not have air permeability, need to be punched after can be used as a desiccant packaging material.
Scope of application: bag desiccant under 20g, low temperature environment
9. Aihua Paper: Aihua paper is an environmentally friendly non-woven fabric without toxicity. Made of special fiber textile, through the paper can clearly identify the internal packaging object, so it is also known as transparent Aihua paper. This material has strong tensile resistance, breathable uniformity, strong sealing degree, high transparency, and good thermal guyron performance. Aihua paper set transparent, beautiful, uniform and other advantages as one.
Aihua paper can be widely used in clothing, craft gifts, shoes, hats and food industries.
Scope of application: bag desiccant less than 20g.
