In recent years, the role of resources and environment in international trade has become increasingly prominent. “Green Barrier” has become the most difficult problem for countries to expand their exports, and some have made a significant impact on the competitiveness of packaging products in the international market. In this regard, we should not only have a clear understanding, but also timely and skillful response. The development of recyclable packaging products meet the requirements of the corresponding countries for imported packaging. Top Pack uses technical regulations and standards that meet the resource and environmental protection requirements of international trade, overcoming technical barriers, and recently vigorously promoting recyclable bags, including snack bags and coffee bags.
What are recycled bags made of?
From promoting your brand to helping the planet, there are many benefits to recycling bags. A common question is where do these recycled bags come from? We decided to take a closer look at recycled bags to help you better understand how customized bags can work for your brand.
Recycled bags are made from different forms of recycled plastic. There are many forms, including woven or non woven polypropylene. Knowing the difference between woven or non woven polypropylene bags is crucial when in the process of making a purchase. Both of these materials are similar and known for their durability, but they differ when it comes to the manufacturing process.
Non woven polypropylene is made by bonding together recycled plastic fibers. Woven polypropylene is made when threads made from recycled plastic are woven together to create a fabric. Both materials are durable. Non woven polypropylene is less expensive and displays full-color printing in more detail. Otherwise, both materials make excellent reusable recycled bags.
Recycled coffee bags
We take coffee bags as an example. Coffee has been climbing the ranks of the most popular drink categories in recent years, and coffee suppliers are paying more and more attention to the packaging requirements of coffee. The aluminum-plastic composite aseptic package utilizes the aluminum foil in the middle layer to provide excellent barrier properties, while the outer paper provides good printing quality. With high-speed Aseptic packaging machine, you can achieve very high packaging speed. In addition, the square aseptic bag can also make full use of space, increase the amount of contents per unit space, and help reduce transportation costs. Therefore, aseptic packaging has become a fast-growing liquid coffee packaging. Although the beans swell during roasting due to the CO2 gas, the internal cellular structure and membrane of the beans remain intact. This allows volatile, oxygen-sensitive flavor compounds to be tightly retained. So roast coffee beans on the packaging requirements are not very high, only a certain barrier can be. In the past, roasted coffee beans were packaged in paper bags lined with waxed paper. In recent years, only the use of PE coated paper instead of the lining of waxed paper.
The requirements of ground coffee powder for packaging are very different. This is mainly due to the grinding process of the coffee bean's skin and the internal cell structure was destroyed, flavor substances began to escape. Therefore, the ground coffee powder must be immediately and tightly packed up to prevent stale, degraded. It used to be ground in vacuum-packed metal cans. With the development of soft packaging, the hot-sealed aluminum foil composite packaging has gradually become the mainstream packaging form of ground coffee powder. The typical structure is PET//ALUMINUM foil/PE composite structure. The inner PE film provides heat sealing, the aluminum foil provides barrier, and the outer PET protects the aluminum foil as a printing substrate. Lower requirements, you can also use the aluminum film instead of the middle of the aluminum foil. A one-way valve is also installed on the package to allow internal gas to be removed and to prevent external air from entering. Now, with technology improvements and improvements, Top Pack also has the technical support and manufacturing hardware to drive the development of recycled coffee bags.
As more and more people like coffee, we must be 100% strictly focusing packaging’s health and safety. At the same time in response to the call for environmental protection, recyclable bags have become one of the requirements from coffee industry’s manufacturers. Top Pack has many years of experience in the production of packaging, including a variety of bags you need and be good at producing recycled bags, we can become a trusted partner.
