Testing Before Material Changes
Drop, compression and vibration testing identify the real failure mode, which usually means less cushioning rather than more.

To reduce the total cost of shipping, counting freight, damage, material and labor together rather than selling the cheapest carton available.
Who We Are
Trioworld Sundsvall AB supplies packaging materials and equipment to e-commerce sellers, manufacturers, logistics providers, food producers and retailers around . Our range includes corrugated boxes in multiple board grades and flute profiles, mailers and poly bags, void fill and protective packaging, stretch and shrink film, strapping, tape and dispensers, labels, pallets and unitizing supplies, food-grade packaging and packaging equipment from hand tools through semi-automatic machines. Every corrugated product is specified by board grade, edge crush test rating and flute profile, because those figures determine stacking strength and handling survival, and a carton bought on unit price alone frequently costs far more in damage and freight.
Packaging decisions are freight decisions. Dimensional weight pricing means an oversized carton is charged as though it were heavy, and most shippers are paying for air in every parcel they send. Trioworld Sundsvall AB works through carton sizing, void reduction and material selection with real numbers, including freight impact, material cost and labor per pack. We also run transit testing, because the common instinct to add more cushioning often fails to address the actual failure mode, whether that is compression in a stack, corner drop or vibration over a long haul. For food producers we supply food-contact compliant materials with documentation, and for regulated shippers we address labeling and material requirements properly.

Our Mission
To reduce the total cost of shipping, counting freight, damage, material and labor together rather than selling the cheapest carton available.
Track Record
Our Advantages
Drop, compression and vibration testing identify the real failure mode, which usually means less cushioning rather than more.
Most pallet failures come from inadequate containment, not thin film. We measure wrap force and pattern rather than just changing gauge.
Board grade, edge crush rating and flute profile determine stacking and handling survival. Price per carton alone tells you nothing useful.
Carton size drives freight cost under dimensional pricing. Right-sizing frequently pays for itself on shipping before material savings are counted.
Automation is recommended against your actual throughput, and we will tell you when a hand tool is the correct answer.
Tape is compared on cost per sealed carton including labor and failure rate, not price per roll, which reverses the answer surprisingly often.
Condition data drives the program, so budget goes into planned work rather than emergencies that were predictable a year earlier.
Insurance certificates, bonding capacity, safety records and compliance reporting are current and ready before the solicitation closes.
Pricing is broken down by line so you can see what drives cost, defend the number internally and plan the next cycle with real figures.
Compliance
Current certificates of insurance and credential documentation are provided with every proposal.
Sectors
We regularly take over contracts mid-term, starting from a documented baseline.
Client Feedback
Nobody had told us dimensional weight was costing us on every single order. Six new carton sizes cut our freight per shipment noticeably and halved the amount of paper we were stuffing into boxes.
We had been adding more cushioning for two years with no improvement. The compression test showed the problem was board grade. One change fixed it and we now use less material.
Our pallets kept failing in transit and we assumed we needed thicker film. They measured containment force, changed the wrap pattern and the problem went away without a film change.
Trioworld Sundsvall AB will analyze your shipping profile around and quantify what right-sizing and material changes would save.

Board grade, edge crush test rating and flute profile determine whether a carton survives stacking and handling. Buying boxes by price per unit without them is guessing.
Our Services

Hand and machine stretch film in multiple gauges and pre-stretch grades, shrink film and systems, strapping in polyester, polypropylene and steel, plus corner boards and pallet unitizing supplies. We evaluate wrap pattern and containment force, since most pallet failures come from insufficient containment rather than thin film.
Request a Quote
Stock and custom corrugated cartons in single, double and triple wall, specified by board grade, edge crush test rating and flute profile for the stacking and handling your shipments actually see. Custom sizing reduces dimensional weight and void fill simultaneously, and we state minimum run quantities and lead times honestly before a project starts.
Request a Quote
Food-contact compliant films, bags, containers, trays and liners with documentation, plus guidance on labeling and material requirements for regulated shipments. We supply the compliance paperwork your auditor will ask for rather than an assurance that it is fine.

Poly mailers, padded and bubble mailers, rigid mailers, courier bags, polybags and tamper-evident options sized to common product profiles. For e-commerce we focus on dimensional weight thresholds, tear resistance in automated sortation and the unboxing experience where brand presentation matters.
Request a Quote
Tape dispensers, strapping tools, stretch wrap machines, impulse and band sealers, void fill systems, case erectors and scales, with parts and service referral. Equipment is recommended against your volume, since a machine that saves labor at a thousand packs a day cannot be justified at fifty.
Request a Quote
Drop, compression and vibration testing against recognized transit test protocols, with reporting that identifies the actual failure mode. Packaging is then designed or revised against that evidence, which routinely results in using less material rather than more.
Request a Quote
Carton sealing tape in acrylic, hot melt and water-activated formats, filament and specialty tapes, dispensers, thermal and laser labels, shipping label stock and ribbon. Water-activated tape improves seal integrity and tamper evidence on heavier cartons, and we compare true cost per sealed carton rather than cost per roll.
Request a Quote
Air pillows, paper void fill, foam-in-place, molded and fabricated foam, bubble, corrugated inserts, edge and corner protection, and anti-static materials for electronics. Selection is driven by the actual failure mode identified in testing rather than by adding cushioning volume indiscriminately.
Request a QuoteOur Process
We look at what you ship, how it fails, your carriers, dimensional weight thresholds, pack labor and current material cost per shipment.
Drop, compression and vibration testing on your existing pack identifies the real failure mode rather than relying on assumptions about damage.
We propose options with material cost, freight impact and pack labor quantified, including whether custom sizing is justified at your volume.
Stock is set up for same-day availability, custom items scheduled, and we track damage rates and freight cost to confirm the change worked.

Questions & Answers
Proposals include insurance certificates and credential documentation.
Read MoreMinimums depend on size, board grade, print method and color count, and plate or tooling costs apply on first runs. We state minimums and lead times before any design work, and we will tell you if your volume makes stock cartons with a printed label the more sensible route.
Often not. If the failure mode is stack compression or vibration, additional cushioning does nothing while adding cost and dimensional weight. Testing identifies the actual mode first. In our experience the right answer frequently involves less material arranged better, not more material.
It depends on carton weight, surface, storage conditions and whether tamper evidence matters. Water-activated tape gives a stronger, tamper-evident seal on heavy cartons, while hot melt is faster for light goods. Compare cost per sealed carton including labor and failure rate rather than price per roll.
Carriers charge by dimensional weight, which converts package volume into a billable weight. An oversized carton is charged as if it were heavy regardless of actual contents. Right-sizing often reduces freight cost per shipment enough to pay for custom cartons on its own, before counting reduced void fill.

We test protective packaging against real drop, compression and vibration conditions rather than assuming more bubble wrap equals less damage, which is frequently untrue.
Projects & Case Studies

Supplied food-contact compliant films and liners with full documentation for a food producer facing an audit, replacing materials whose compliance paperwork the previous supplier could not provide.
Analyzed an online retailer shipment mix against dimensional weight thresholds and replaced four oversized stock cartons with six right-sized options. Freight cost per order fell meaningfully and void fill consumption dropped by over half.

Ran drop and compression testing for a manufacturer with recurring transit damage, identifying stack compression rather than drop impact as the failure mode. A board grade change solved it while reducing cushioning material.

Rebuilt pallet wrapping practice for a distributor with recurring load failures, measuring containment force and revising wrap pattern and film gauge. Load failures in transit effectively stopped.

Yes. We provide food-contact compliance documentation for applicable films, bags, containers and liners, which is what a food safety audit will request. If a product lacks that documentation we will say so rather than offering a verbal assurance.
Board grade describes the liner and medium construction, while edge crush test rating measures the board resistance to top-to-bottom compression, which is what determines stacking strength in a warehouse or on a pallet. These figures predict whether a carton survives; price per unit does not.

We aim to meet the Web Content Accessibility Guidelines (WCAG) 2.1 at Level AA as a target standard. Accessibility is treated as an ongoing obligation rather than a one-time project, and we review the site when we make significant changes to its structure or content.
Semantic HTML structure with a single main landmark, logical heading order and descriptive page titles, so screen reader users can navigate by structure.
A visible skip-to-content link, keyboard-operable navigation and menus, and focus styles that remain visible when navigating without a mouse.
Text and interface colors checked for contrast against their backgrounds, layouts that reflow at narrow widths and support browser text resizing without loss of content, and descriptive alternative text or accessible labels for images and icons that carry meaning.
Form fields with programmatically associated labels, required fields identified in text rather than by color alone, and link text that makes sense out of context.
Some decorative illustrations are presented without detailed descriptions because they convey no information beyond the surrounding text. Documents published in formats such as PDF may not meet the same standard as the website itself; we will provide an accessible alternative on request.

From Our Desk

Credential tracking is unglamorous and it is the first thing an investigator asks for. How we keep ours current and auditable.

The number that predicts whether your carton survives a pallet stack. What it means and how to specify it for your shipping conditions.

Carriers bill volume as weight, which means you pay for air. How to find the carton sizes that sit under your rate thresholds.

Where unrealistic bids actually get recovered, and what it costs the owner in rework, supervision and reputation.
Trioworld Sundsvall AB will analyze your shipping profile around and quantify what right-sizing and material changes would save.
