Friends who make FFS heavy-duty bags, please have a look. We have independently developed heavy-duty bottom-seal bag-making machines. After years of upgrading, we have independently developed heavy-duty bottom-seal bag-making machines. Our new bottom-seal bag-making machines have been upgraded to 5 servos, with two servos for front and rear feeding, one servo for the flying knife, and one servo for the silicone sheet workbench. For a single bag, the total thickness can reach 1.2 mm. We have also launched a number of products in this series, including center-seal forming heavy-duty packaging equipment, maze exhaust tube making equipment, and square bottom valve bag making equipment. Friends who are interested can contact us, and let us explore FFS heavy-duty packaging bag making together.
