When it comes to industrial packaging solutions, Block BOPP Bags (also known as Block Bottom Bags or Block Bottom Woven Bags) have emerged as a key product for a variety of industries. The unique design and structure of these bags offer a distinct advantage in terms of stability, stackability, and durability, making them an ideal choice for packaging and transporting products that require reliable, heavy-duty solutions. At VidePak, we take pride in offering top-tier Block Bottom Woven Bags that meet the highest industry standards, from design to raw material sourcing and manufacturing processes. In this article, we will explore the key features and benefits of Block BOPP sacks, along with the stringent quality control procedures we follow to ensure that the raw materials used in their production are of the highest quality.
One of the main reasons for the popularity of Block BOPP Bags is their robustness and versatility. These bags are particularly useful in packaging agricultural products, chemicals, and other bulk materials. The Block Woven Bags provide a sturdy base that allows them to stand upright, making them easier to fill, handle, and store, which is especially beneficial for supply chain efficiency. The durability of these bags, combined with their functionality, has made them an indispensable product in global markets.
To ensure that our Block Bottom Bags meet the highest quality standards, we source the raw materials from some of the world’s most respected suppliers, such as SINOPEC, CNPC, YPC, and Hengli Group. These manufacturers are known for producing high-quality polyethylene (PE) and polypropylene (PP) plastic pellets, which are the core materials used in our woven bags. It is crucial that the raw materials are of the highest quality because the durability, strength, and reliability of the finished bags depend directly on the quality of the pellets used.
Raw Material Sourcing and Quality Control
At VidePak, we strictly adhere to international standards in sourcing and quality control. We do not compromise on the quality of our raw materials. We source only 100% virgin PE and PP pellets for the production of our Block BOPP Bags and Block Woven Bags, ensuring that the bags are durable, safe, and resistant to wear and tear. The use of virgin pellets helps to prevent the issues commonly associated with recycled plastics, such as brittleness, contamination, and inconsistency in material properties.
The raw materials undergo rigorous quality checks before they are used in production. Upon arrival, the materials are tested for purity, color consistency, and other quality metrics to ensure that they meet our exacting standards. We work closely with our suppliers to guarantee that the pellets we receive are free from any defects or impurities that could affect the final product’s strength and longevity.
To ensure consistency, we perform a series of tests on the raw materials before they are integrated into the production process. These tests include:
- Melt Flow Index (MFI) Test – This test measures the flow rate of the material when heated to a specific temperature. It is an important test that helps us determine the material’s processability and overall quality.
- Tensile Strength Test – This test measures the material’s ability to withstand tension without breaking, ensuring that the Block Bottom Bags will be strong enough to handle the contents securely.
- Density Test – Density is an important factor in determining the material’s strength. A higher density typically results in stronger, more durable bags.
- Moisture Content Test – Excess moisture can lead to defects in the bags and reduce their effectiveness. Moisture is tested to ensure that the material is dry before processing.
- UV Resistance Test – To ensure that the Block BOPP Sacks perform well in outdoor or high UV exposure environments, we conduct UV resistance tests to assess how the material holds up to sunlight.
Advantages of Block BOPP Bags and Block Woven Bags
Block BOPP Bags and Block Bottom Bags have become the go-to solution for many industries due to their unique combination of strength, versatility, and sustainability. Here are some of the key advantages of these bags:
