FAQ

Q1: For a new product, what's the first step in choosing packaging material for VFFS Machine ?

A: Start by defining your product's core needs, such as its required moisture/oxygen barrier and target shelf life. This will significantly narrow down your material options before you even consider cost or machine compatibility.

Q2: My seals are inconsistent. Is it the film's fault or my VFFS machine's?

A: It's often a combination. First, verify your machine's sealing temperature and pressure are correct for the film's specifications. If the problem persists, the issue could be inconsistent film quality or thickness.

Q3: Are sustainable or paper-based films strong enough for high-speed VFFS machines?

A: Yes, modern sustainable laminates are engineered for strength and performance on high-speed lines. However, they may require minor adjustments to your machine's temperature and tension settings for optimal results.

Q4: What's the quickest way to lower my film costs without risking product safety?

A: Consider "downgauging" to a thinner film that offers equivalent barrier properties. Alternatively, evaluate if a simpler material like PE or PP can meet your needs instead of a more expensive laminate, but always test thoroughly before switching.

Q5: What does it mean when a film is a laminate, like PET/PE?

A: A laminate combines layers to get the benefits of each, like PET for strength and printability on the outside and PE for a reliable seal on the inside. This structure provides superior performance that a single material cannot offer alone.
