What is the difference bwtween wet press molded pulp vs dry press molded pulp Molded pulp is one of sustainable packaging material. Do you know how to distinguish wet press molded pulp and dry press molded pulp? In below chart, I will explain the difference one by one.    Wet press molded pulp Dry press molded pulp Mold cost Lower Reference: 2000USD~3000USD Depends on size and design Higher Reference: USD4000-5000USD Depends on size and design Unit price Relatively Lower Relatively high Material preferred: recycled cardboard Other options: sugarcane bagasse paper White paper sugarcane bagasse paper white paper bamboo paper kraft paper Surface One side is very smooth, the other side has mesh texture One side is relatively smooth, the other side is

To answer this question, you have to know how the mushroom packaging is made first. In short, it is using crops waste as structure substrate and adding special fungus to develop its mycelium to combine all raw materials and solidify together in the mold. Usually, the mold is vacuum formed mold and the mycelium grow in the mold to expected dimension and shape. This process usually takes 3 days, then we remove the formed mushroom packaging from mold and dehydrate it. You can understand the shape and dimension of the mold decide the final mushroom packaging. Talking from the production aspect, there is indeed a size limit for the cut-out tray for mushroom packaging like below. It is at least one dimension

Mushroom Packaging could be used as alternative for foam plastics that to be used for products package, when it completed its usage, mushroom packaging could be disposed and degradation in nature as plant food, OR, recycle by manufacturer.

Production Process of Mycelium Packaging ( Mushroom Packaging)   Mycelium packaging or some people may call it mushroom packaging is a kind of creative sustainable packaging material. It is simply made with cornstraw and mycelium and able compostable in soil within 60 days. Its outstanding properties is but not limited to: full biodegradable, no chemical additives, no heavy metal, nontoxic, no irritating odor, fireproof, light density, high impervious, good cushioning, insulated, adiabatic, shock absorption, thermal insulated, recyclable or collect to be bio-fertilizer. It can be used as product packaging cushioning, interior functional decoration, food insulation packaging, that to replace corresponding white pollution plastic products: EPS, EPE, PU foam. In next, I’d like to introduce the production process of mushroom packaging to you.

For most of the vest bags that used in supermarket or other shops, they are plastic. While with the ban on plastic bags and the growing awareness of environmental protection, more and more shops are using sustainable, biodegradable shopping bags. In next, I’d like to introduce the commonly used materials for the plastic vest bags and their advantage or disadvantage comparing to each other. Project Item Fully Degradable material Half Degradable Material Traditional Materia Main Material Corn Starch+ Fully Biodegradable resin biodegradable material +PE PE Tenacity Low (because of non-PE content, so the tenacity is relatively low than ordinary plastic bags) Medium High Degree of degradable It can be completely degraded in a certain time without harmful residue The degraded material will
