Questions And Answers

Frequently Asked Questions

Everything buyers ask us before ordering, grouped by what you are trying to work out. Every specification quoted comes from a published data sheet.

Products

What does Jiamei manufacture

Ventilated stretch film, bale netwraps and pallet nets. Four products are published with full technical data: two ventilated film grades and two pallet netting grades.

What is ventilated stretch film

A perforated stretch film designed to maximise the aeration of the product wrapped. Because of its perforated structure it allows quicker cooling and drying of palletised goods.

How many perforations does the film have

Thirteen holes in every row, on both the prestretchable and the prestretched grade.

What is the difference between JMSH01 and JMSH02

JMSH01 is prestretchable, 25 microns, 500 mm wide, stretched on your wrapper up to 230 percent, with 26 kg tensile stress at break. JMSH02 is already prestretched, 8 microns, 430 mm wide, with 15 kg tensile stress at break and 3.1 g per metre.

What is the difference between JMSH02 and JMSH03

They share the same technical data sheet and specification. The difference is the roll format supplied, so tell us whether you need machine rolls or manual rolls.

What are the pallet nets made from

The standard grade is 100 percent virgin HDPE. The elastic grade is 100 percent virgin MPE with a stretch rate of 15 to 50 percent, determined by the weight of the load.

Do you supply bale netwraps

Bale netwraps are part of our range. We have not published a data sheet for them on this site, so ask and we will send the current specification rather than guess at the numbers.

Specifications And Formats

What roll lengths are available for film

1300 m machine rolls in the prestretchable grade, 3500 m machine rolls and 440 m manual rolls in the prestretched grade.

What roll lengths are available for netting

Manual rolls of 500 m to 1000 m and automatic rolls of 3000 m to 4000 m. Manual and automatic use are both available.

What netting widths do you supply

30 cm, 50 cm and 76 cm, in both the standard and elastic grades.

What core diameter do netting rolls have

3 inch or 2 inch inner core diameter, supplied to your request. Confirm your wrapper mandrel before ordering.

Can products be customised

Yes. Ventilated stretch film and pallet nets can both be customised to your request, including roll length, web width and inner core diameter.

What tolerances apply to the film

Width to five percent, average thickness to two microns, weight per metre to five percent, and grade specific tolerances on elongation and tensile stress. All are published on the product pages and data sheets.

Choosing And Applying

Which product suits a warm pallet best

Pallet netting has the largest open area and is the strongest choice for the warmest and wettest loads. Ventilated film gives more surface protection while keeping thirteen holes open per row.

Which grade for heavy loads

JMSH01 at 25 microns, with 26 kg tensile stress at break and 250 percent elongation at break.

Which grade for the lowest plastic weight

JMSH02 prestretched film at 3.1 grams per metre, or pallet netting, which is mostly open space.

My wrap is tight at dispatch and slack on arrival

The load is settling. Elastic MPE netting stretches 15 to 50 percent depending on load weight and recovers as the pallet compresses.

My film breaks at pallet corners

The prestretch setting on the wrapper is probably too close to the film elongation at break. Lower it one step and re run a pallet, then check for sharp case edges.

Can I wrap by hand

Yes. The prestretched film comes on 440 m manual rolls weighing 1.37 kg, and netting comes on manual rolls of 500 to 1000 m.

Ordering And Support

How do I get a quotation

Message us on WhatsApp or send an email with your pallet size, load weight, wrapper model and the temperature at which goods are wrapped.

Can I get samples

Tell us which grades you want to compare and we will confirm what can be sent for a trial on your own wrapper.

Where is the factory

Qianbei Industrial Park, Baotian Village, Tangxia Town, Ruian City, Zhejiang Province, China, close to Wenzhou airport and Ningbo port.

What certifications do you hold

We have not published certificate scans on this site. Tell us the destination market and the goods on the pallet and we will send the documentation that applies to your order during sampling.

Do you have case studies

We do not publish customer case studies. We would rather work through your own load with you and let a trial roll on your line be the evidence.

Do you have an enquiry form

No. WhatsApp and email are direct, and they let you send a photo of the pallet, which a form does not.

Still Not Answered

Send the question with your pallet details and we will answer it directly rather than adding another page.
