HDPE (high-density polyethylene) is a largely utilised thermoplastic that maintains multiple advantageous properties, such as rigidity and excellent chemical antagonism. Although a portion of the polyethylene family, HDPE has a molecular thickness that is extensively increased than that of its standard companion, which gives it distinctive mechanical properties. In this article, we will talk about the main benefits & drawbacks of HDPE Plastics Bags and analyse the various industries that make the most of this remarkable polymer.
The main Advantages of HDPE
Resistant to Chemicals
Distinguished by high antagonism to eroding, HDPE is an epitome fabric for manufacturing storage containers for fluids, food, and chemical derivatives with varying pH levels. Thanks to this characteristic, it can conserve its properties when about chemicals, thus staying secure and useful.
Certified Food Grade
Many industries opt for HDPE for food and liquid storage because it fulfils FDA sanitary criteria. Safe for contact with foodstuffs and comfortable to clean, HDPE is a wise option for food environments where protection standards are a significant problem.
Durable and Lightweight
The density of HDPE varies from 941 kg/m3 to 965 kg/m3 relying on its formulation. By comparison, although aluminium is mulled extremely light, it has a density of 2699 kg/m3, nearly 2.8 times heftier than HDPE.
UV Resistant
UV resistance is a crucial property that assures the optimum service life of parts and components that are largely utilised outside. Unlike different plastics, HDPE has various UV-resistant formulations. This creates an ideal bag for outdoor applications. HDPE comprises a UV stabiliser varied with its resin.
Easily machinable and Weldable
High-density polyethylene can effortlessly be machined or soldered. These enduring, strong welds make it possible to formulate bigger projects, such as big watertight tank liners utilised to stock important volumes of liquids.
Does not Absorb Moisture
Zero moisture absorption is a crucial part of fabrics utilised for liquid and food storage. For this justification, HDPE is an extraordinary possibility when designing storage tanks and other products designed for outdoor use because it does not soak vapor even when subjected to prolonged contact with fluids.
The main areas of use for HPDE
Food
Various HDPE formulations comply with FDA and European standards and are therefore authorised for immediate relation with food. An HDPE evolved especially for the food industry and is utilized almost exclusively in the manufacturing of stringent, enduring, and easy-to-clean cutting boards. These bags are food safe and do not damage any food items.
HDPE is also an excellent alternative for environments controlled by stringent sanitary standards.
Medical and pharmaceutical
HDPE is frequently utilized in the medical field, as it does not soak up vapor and offers outstanding chemical resistance. Nontoxic and food grade, HDPE is excellent for work textures or warehouse units such as medical containers. Some formulations that contain particular plastic additives also have antibacterial properties.
Chemical
Because of its high chemical resistance and weld ability, HDPE is a fabric of choice for the design of bottles, containers, and tanks planned for chemical products. It is also utilized to create corrosion-resistant liners. High-density polyethylene is consistent with many products.
Construction
As spoken of earlier, HDPE does not soak water and can be efficiently soldered. This clarifies its popularity. Various properties of HDPE bags make them a perfect material for designing lightweight, strict, and stable packaging systems.
Disadvantages of Plastic Bags
Plastic bags have a broad range of benefits but the list of drawbacks that it has is relatively never-ending. This is due to the only truth that plastic is non-biodegradable. If you discard plastic in a little quantity of the soil then even after a specific period, the plastic would remain unaffected in the soil.
This means that it does not get soaked into the soil or also deteriorate in the existence of the microorganisms which are present in the mud. This leads to the proliferation of plastic in the climate thus, resulting in plastic pollution.
We use plastic bags then after their usage is over we put them in the dust bin. This plastic trash is not dealt with and therefore, is ditched into the forest, and oceans, or also buried in the soil without any treatment. This just leads to the accretion of plastic.
The garbage bag itself is created of plastic which again contributes to plastic pollution.
Also, plastic takes more than 1000 years to contaminate by breaking it down into lighter toxic substances and not into biologically beneficial ethylene.
The plastic trash which is thrown out into the oceans affects marine life on a very large scale. The fishes living in the sea cannot breathe as low-density plastic floats on water.
This floating of the plastic might obstruct or would not permit the Fish to inhale and exhale (i.e. access to oxygen).
Even if they arrive at the surface a foreign substance like plastic impedes their ecological cycle as they misunderstand plastic to be food (prey fishes like jellyfish) and consume it. It is normally said that sea turtles ingest such plastic bags or balloons which eventually leads to their extinction.
Therefore, plastic pollution has also been deemed a threat to aquatic life and also a possible reason for the contraction of the number of certain species of turtles. Plastic is also dumped or concealed in the soil. As understood above, plastic degrades very slowly, that is, it takes 1000 years to lessen.
But the degradation is also too poisonous to the climate as plastic ruptures down into harmful components which are harmful to the plants thriving in that soil. The consumption of plastic by animals can strangle them and cause unfortunate extinction. Also, the proliferation of plastic in soil degrades its nutritional quality.
This also impacts the plants and trees which thrive in the soil. Most of the time it is deemed that burning plastic can deteriorate it but this is not the case. The burning of plastic bags causes them to dissolve and develop harmful poisons in gaseous forms which if inhaled can induce suffocation or also the expansion of these toxins in the body.
Singhal Industries Pvt. Ltd. is the best Fibc bulk bag manufacturer in the country. If you are planning to purchase any kind of bag, then you can also choose from these PP Jumbo Bags, PP Woven Bags, Woven PP Bags, HDPE Bags, PP Woven Bag etc.
