Frequently Asked Questions (FAQ)

My goods have sharp carton corners and metal edges. Hand stretch film keeps getting punctured during wrapping. What should I do?

A: For goods with sharp edges and corners, we recommend a hand stretch film with an improved tear-resistant formulation. Its enhanced tear resistance reduces the risk of puncture during wrapping and minimizes rework and rewrapping. If there are many sharp points and the load is heavy, you can also trial a metallocene-modified machine stretch film used together with edge protectors. We suggest requesting samples and running an actual wrapping test on site.

How do I choose the right specification for hand stretch film? Is thicker always better?

A: Selection should not be based on thickness alone — it requires a combined assessment of load weight, whether there are sharp corners, and wrapping frequency. We offer hand stretch film in a range of low net-weight specifications. For companies with small-batch wrapping needs, choosing the right specification avoids overstocking and waste of large rolls. With the same raw material formulation, toughness and tear resistance affect actual wrapping protection more than thickness alone. You can request samples for a hands-on comparison test.

What is the net weight per roll of hand stretch film? Are weight and length accurate? Can you make smaller, lighter rolls?

A: Our hand stretch film is available in multiple roll weight grades, including low net-weight rolls suited to one-off replenishment and temporary wrapping needs. This reduces startup waste on small purchases and avoids long-term inventory buildup. All products are manufactured under fully digitalized quality control, with specifications produced according to order agreements. For specific roll weight and length figures, please consult our sales team.

When wrapping with hand stretch film, the layers don't stick together and the load loosens or slips after wrapping. Why?

A: Our hand stretch film uses a moderate-cling formulation. Under normal wrapping with proper tension, the layers bond tightly, reducing the risk of loads coming apart in transit. If layers fail to stick, common factors include: ① insufficient stretch, so the film does not make full contact; ② low ambient temperature, which slightly reduces cling; ③ dust or moisture on the cargo surface. We recommend keeping cargo surfaces dry and applying moderate stretch with overlapping wraps. In low-temperature winter warehouses, store the film at room temperature indoors before use.

Why does hand stretch film sometimes break suddenly during manual wrapping?

A: Our hand stretch film uses an improved formulation with good tear resistance and does not break easily under normal manual operation. Besides the film itself, breakage can also be caused by excessive stretching force, sharp edges cutting directly into the film, or low storage temperatures making the film brittle. If breakage occurs frequently on site, contact our sales team with your operating conditions and photos so we can help troubleshoot, or request samples for an on-site comparison test.

Within the same purchase batch, why do some rolls pull smoothly while others are hard to unwind?

A: We apply quality control across the entire process, keeping stretch force and cling as consistent as possible from roll to roll. This reduces variation in unwinding feel, keeps the wrapping experience stable for workers, lowers training costs, and delivers uniform packaging results. If you notice differences in feel upon receipt, first check storage conditions — large temperature swings, or rolls exposed to freezing or heat, will change the unwinding feel. If anything seems abnormal, contact your sales representative with details of the conditions.

Does hand stretch film leave adhesive residue on cargo surfaces?

A: Hand stretch film uses self-cling between layers, not adhesion to the cargo surface, so under normal use it leaves no residue on goods. However, prolonged storage in high temperatures or direct sunlight, or storage beyond the shelf life, may cause performance changes. We recommend storing in a cool, dark place and using unopened rolls within 12 months.

What is the minimum order for hand stretch film? Can I get samples to test? Do you support customization?

A: Samples of standard specifications are available on request — we recommend testing on site before placing a bulk order. Standard stock items have a corresponding minimum order quantity. For customized width, color or other parameters, a custom MOQ applies. Please consult our sales team to confirm minimum quantities and sampling lead time.

For long-term purchasing, will quality vary between old and new batches?

A: We work in close partnership with leading upstream raw material suppliers and source materials directly at the source. We operate our own testing laboratory and monitor thickness, stretch force and cling online on the production line. With a closed R&D-production-sales loop driving continuous process refinement, we keep batch-to-batch variation to a minimum, ensuring stable feel and wrapping performance over the long term and reducing inconsistency between old and new batches.
