Plaster and cement plastic

Plaster and cement are the most important materials in construction. With the increasing construction, the demand for these products also increases. One of the important requirements for maintaining these widely used building materials is their storage and maintenance conditions. Today, plaster and cement factories use plaster and cement plastic or polyethylene bags to package and present their products, which has attracted the attention of this industry due to its high resistance and relatively cheap price.

Features of plastic packaging plaster and cement

Plaster and cement are very sensitive to moisture and water penetration, and if they are exposed to these factors, they become lumpy. Sometimes the lumps become so hard that they cannot be crushed by hand. As it is clear, the materials containing these lumps cannot be used for construction works. Therefore, plaster and cement must be stored in a dry and moisture-free environment, and the cement packaging bags must be completely resistant and impermeable to the penetration of foreign materials and moisture. Another point that should be taken into consideration regarding plaster and cement bags is the flexibility of the bags. These bags are continuously transported and moved until they are used. Loading from the factory to the truck, unloading from the truck to the project site, transportation from the unloading site to the warehouse, transportation from the warehouse to the consumption site all indicate the frequent movement of plaster and cement bags. For this reason, these bags must be very resistant and flexible so that they do not tear due to these movements and to minimize the wastage of cement during transportation. According to the mentioned conditions, market experts and civil engineers consider the best way to store and pack plaster and cement to use plastic bags and envelopes, which are of high quality.

Advantages of plastic over other packaging

Until the past few years, paper envelopes were used to pack and transport plaster and cement. The biggest problem of these envelopes was the possibility of water infiltration into them, which, in addition to tearing and getting wet, led to hydration and rotting of the cement inside them. These envelopes also had a low weight bearing capacity and a high cost due to the use of paper in them. In addition to paper envelopes, in the past, hemp bags were also used to move cement, plaster and sand, which gradually became obsolete. The most important reason is the coarse texture of hemp sacks, their high cost compared to plastic bags and their heavy weight. Today, instead of hemp and paper bags, they use simple or laminated plastic bags that are completely resistant and waterproof.

Construction material bag printing

With the increase of factories producing construction materials, it is necessary to include information and product specifications on their packaging bags. Printing on plaster and cement sacks and bags, in addition to being an advertising method to introduce the manufacturer’s brand, provides the possibility to print the necessary information such as safety recommendations and product descriptions on the packaging. For this purpose, it is better to use bags that can be printed on for sacking construction materials. As you know, the fibers that make up plaster and cement plastic are a polymer material called polyethylene, which makes it easy to print on plastic sacks due to the fact that the ink does not spread on the bag and its durability on the fibers.

Frequently asked questions

1. What is a laminated plastic sack? Laminate is a layer of compressed plastic that is added to sacks and bags for waterproofing and more strength.
2. What is the capacity of each bag? Plaster and cement are often supplied in bags of 5 to 25 kg.
3. What problem does the infiltration of moisture into plaster and cement bags cause? It causes them to become lumpy or rotten. Deterioration of plaster and cement occurs when these materials lose their properties, for example, when mixed with water, their volume does not increase or they do not find the necessary hardness.
4. How to store and maintain bag plaster and cement? In dry areas, we can stack 12 plaster or cement envelopes on the condition that the height does not exceed 1.8 meters. Also, the bags should be arranged at a distance of 5 to 8 cm from each other, 10 cm from the floor and 20 cm from the warehouse walls.
