How To Produce A Stronger Film With A Lower Cost?

Hello everyone this is Sara from Howie Machinery Sales department.Today I'm going to tell you the advatage of ABA Blown film machines for Pe bag production.single layer blown film machine has been the most common type of extruder to use it is probably still the best machine for products such as fruit and vegetable bags that use mainly virgin materials with low film thickness ranging from 6 to 18 microns.Single layer machine is also the favorite for biodegradble bag production.Even though single layer extruder is more than enough for general back production ABA co-extrusion machine has its advantage over one or two layer machine for certain applications like garbage bags,shopping and T-shirt bags that are higher in thinckness or require more film strength.In markets such as Oceania and North America,producing large-sized garbage bag with ABA-co extrusion lines has already become the new industrial trend.

Besides having the ability to produce film with higher strength ABA blown film extruders also allow producers to use more recycled material and calcium carbonate (CaCO3) in a mixture.The advantage is clear especially when producing film in higher thickness,in which material cost can be significantly reduced while good film quality can still be maintained.In coutries where bag production market has become extremely competitive,some producers have started to change form single layer extrusion to ABA co-extrusion blown film machines in order to reduce production cost and stay competitive New grgylations in Europe also require bag producers to use a higher percentage of recycled material for shopping bags and garbage bags,whether they are produced locally or imported.

So,What makes ABA machines so special for bag production?First,technically speaking,in ABA type film the outer and inner layers will be of the same material fed by the same extruder and middle layer will be of a different mateial the same material fed by the same extruder and middle layer will be of a differnt materil that will be fed by a second extruder.A higher percentage (up to 50-70%) of calcium carbonate or recycled material can be used in the middle layer of the film,thus cutting down the usage of virgin raw material and reducing production cost.Second,besides reducing a significant amount of raw material used in the formula,another advantage of the ABA machine is that the 3-layerd film which produces is 30% stronger than the mono-layer film produced by a single extruder.Finally,ABA has only two extruders whereas ABC has three extruders.In most bag applications where producers can use the exact same material in the outer and inner layers,ABA can achieve the same result as ABC(in terms of film strength and material cost reduction),while saving on the machine investment and electricity cost.The fact that single layer and ABA machines each has its advantage over the other,many film and bag producers use a combination of both machine types to target specific products of different width thickness and recycle materials allowed,in order to achieve the maximum production efficiency.

Howie Machiery has specially designed extrusion screw to work with the highest possible percentage of recycled material whether it is a single layer or ABA machine.This allows the film producers to be more flexible when making different products with different formulas and materials.Are you ready to expand your production line with our HY-FM blown film machine?
