4 kinds of molded fiber pulp packaging the best raw materials

Table of Contents

The best raw materials for molded fiber pulp packaging include recycled paperboard, agricultural residues, virgin wood pulp, and bamboo. Recycled paperboard reduces water use by 70%, while bamboo grows quickly, harvesting every 3-5 years, offering sustainability and durability.

Recycled Paperboard and Newsprint

Recycled paperboard and newsprint are the ideal raw materials for molded fiber pulp packaging for two reasons. The materials are readily available in a large variety of supply, and it is sustainable. The process of manufacturing products from recycled paperboard results in a lower environmental impact because it eliminates the need for virgin fibers and reduces the impact of deforestation and use of landfills. Secondly, in terms of their general production process, tangible benefits from the sustainability point of view include a 30-40% reduction in water usage. The reduction reaches as much as 70%. Similarly, energy usage will also be reduced by 30-40%, as much as 40%.

A standard molded fiber tray, which may be produced by a company at a rate of 1,000 trays, uses 1.2 kWh of energy when the trays are made of scrap materials. This is a significant difference from those made from virgin materials, which use 2.0 kWh. The material, recycled paperboard, used significantly lowers costs – around $60 per ton for recycled paperboard compared with between $100 and $250 per ton for virgin wood pulp.

Everything that is made of scrap materials made from the store-selling newsprint, such as egg cartons, apple, and coffee cup trays, is also quite strong and will biodegrade. The rigorous course involved in providing molded trays for eggs or apples is approximately 10 lbs of pressure per tray, at which point the pressure starts to leave a trace. The use in the recycling industry of recycled paperboard maintains the life-cycle view of business; hence, its continued development in the field and job growth around recycling and production plants must be promoted.

Agricultural Residues

Currently, more and more researchers consider agricultural residues as highly efficacious raw materials for molded fiber pulp packaging. First and foremost, this trend can be supported by their availability and associated environmental benefits. Sugarcane bagasse, wheat straw, and rice husk are byproducts of agricultural production that can be transformed into pulp used for producing packaging.

Agricultural residues can lead to a significant reduction of the wood pulp use and,  contribute to the preservation of forest resources and biodiversity. It is estimated that the production of molded fiber packaging utilizing sugarcane bagasse requires 30 percent less energy in comparison to that of wood pulp. Additionally, as white paper notes, this molded fiber is often used in making takeaway food containers. They can withstand temperatures of about 200 degrees Celsius and therefore are suitable for use with hot food, thus substituting non-biodegradable polystyrene containers.

Second, one of the main benefits of the use of agricultural residues in the production of molded fiber pulp packaging is their cost. Due to the characteristics of economies of many farmers, residues of sugarcane, wheat, and rice threshing are not considered as primary power. On the contrary, they are seen as surplus biomass that has accumulated as a result of the clearing of manors, usually due to the need to grow a new culture. As a result, these biomass residues have a small price, and the cost of wheat straw is around $45 per ton, which is much lower than the price of traditional packaging raw materials.

The difference in this characteristic is compounded by their availability since a large number of such wastes are formed in agricultural countries and can be easily supplied to a nearby farm, warehouse, or factory. Third, their practicalities are high, as they are involved in products with relatively low costs for the end consumer. Such products include trays, plates, bowls, and fast food containers sparkling on the kitchen lanes of fast-food restaurants and cafes. The molded fiber pulp packaging is also relatively resistant to oil and other loads.

Virgin Wood Pulp

Virgin wood pulp is the primary material for molded fiber pulp packaging, as it is more robust, whiter, and more consistent than most alternatives. This pulp is produced from trees and is most likely derived from fast-growing species with management complying with sustainable forestry regulations. There is a significant benefit in the use of virgin wood pulp caused by the high quality of the material, as it is more robust and, as a result, more reliable for the production of, for example, luxury packaging for consumer electronics or cosmetics.

Virgin wood pulp results in a more consistent and whiter material, which offers excellent properties for high-quality printing or branding. Finally, one of the primary advantages of using virgin wood pulp is its impact on the production process. Pulp made from virgin wood needs fewer layers to achieve the strength of its recycled counterparts, which can result in a 15% time reduction and material savings. While the main disadvantage is the tier-two average price of $800 per ton, it can be fully justified with the help of manufacturing effectiveness arguments listed above.

Virgin wood pulp is characterized with lower impact on the environment not only because of its biodegradability and recyclability, as opposed to plastic, but also because it is produced and harvested in sustainable forestry program with the following replanting. The use of sustainable forests allows reducing the harmful effects on a natural environment in general, and these practices ensure a constant supply without undermining the natural resources. It is often used in industries, where hygiene takes precedence, such as food or medical packaging.

Many food product packages have numerous layers, and many of them come in direct contact with food and are made with virgin wood pulp mainly because recycled fibers might contain harmful elements or substances that the product should not be in contact with to guarantee the highest level of safety, as it is often the most important regulatory requirement in these industries. By choosing virgin wood pulp, companies are selecting a premium material that is impossible to replace by an alternative due to its level of quality and performance in certain applications. At the same time, if conducted responsibly, the forests are sustainable, and the long-term effects of these practices will not lead to the replacement of a non-renewable resource like a regular tree.

Bamboo

Bamboo has become one of the best sources for molded fiber pulp packaging over the years. It is both sustainable and an excellent renewable resource. It has become a material of choice in eco-friendly markets, and with good reason – it has several implications for the environment and the economy alike. Bamboo is a highly renewable material that allows for quick regrowth while providing considerable cost benefits to utilizing it.

Rapid Growth and Renewability

Bamboo grows exceptionally fast, with the maximum growth rate of some species being 91 cm in a 24-hour period. This makes the material very renewable, as it can be harvested every three to five years, unlike hardwood, which may need as much as twenty to fifty years to reach maturity. This quick turnover of materials allows for the resource to be harvested often without causing a large-scale ecological collapse.

Economic Advantages and Efficient Use of Materials

Bamboo is considerably cheaper to utilize than any other material, especially the one traditionally utilized, such as plastic. The general cost of producing fibers for such packaging usually does not exceed $500 per ton. This price is primarily due to the high cost of petroleum fuel used to produce synthetics, as well as the technological process involved in making such materials. Additionally, bamboo is naturally strong and flexible while being very lightweight. As a result, many containers and packaging boxes are produced with less material than their heavier and denser counterparts. For instance, the takeaway containers used in a multitude of retailers around the world, are generally used in bamboo box sizes. Furthermore, it does not make the product too lightweight and still serves to protect it.

Practical Applications

Practical uses for bamboo include any kind of packaging, such as protecting perishable foods, electronics, and other products. The products in question include plastic cutlery and biodegradable serviceware provided by a variety of restaurants and even used for catering. This also has the benefit of safety for the consumer, as, when heated or stored in a similar temperature or humidity, the bamboo does not change shape or transfer flavor. With bamboo being resistant to molds and having a certain level of mold protection, it is ideal for packaging perishable goods.
