Case

Client Profile:Beauty and skincare brands serving North America and European markets (primarily DTC independent sites, with Amazon channels as a secondary focus) Core Requirements:Leak and breakage prevention, brand visual presentation, compliance and market access, enhanced unboxing ritual 1. Project Background We were approached by a skincare brand that had been operating in the U.S. market for over three years. Their flagship product line is a three-piece gift set containing serum, face cream, and toner, priced in the near-$100 range and positioned as an affordable luxury. On paper, the numbers looked decent. But when the brand reached out to us, they were grappling with three major pain points: First, an unacceptably high rate of shipping damage.Both the serum and toner are packaged in glass bottles, and during transit they frequently suffered cracked bottles and leaked product. According to their customer service team, “damaged packaging” and “liquid leakage soiling the parcel” together accounted for nearly 30% of all return reasons. After every major sales event, the support team would be buried in refund requests and negative reviews for days. Second, a thoroughly underwhelming unboxing experience.Customers received a plain five-layer corrugated carton stuffed with a few haphazard wraps of bubble film. Products rattled around loose inside, and there wasn’t even a thank-you card. One returning customer wrote in a review: “Opening it felt like receiving a return from the shipping company.” For a brand selling a nearly $100 gift set, that kind of feedback is devastating. Third, incomplete compliance documentation.Their previous supplier — a small domestic factory — could not provide FSC certification or FDA food-contact material reports. Shipments were routinely held up at U.S. Customs for days, delaying delivery timelines and dragging down store ratings. 2. Hanlong’s Solution Rather than rushing to quote, Hanlong asked the client to ship a product sample set to our facility so we could study their entire storage, packing, and shipping workflow. Based on this hands-on product and packaging assessment, we developed a comprehensive upgrade plan covering every layer of the package. a. Leak-Proof Sealing Structure For liquid products like serums and toners, leakage is the biggest headache. We designed individual internal compartments within the outer box — every bottle gets its own “assigned seat,” eliminating collision and tipping during transit. For the face cream jar, the inner tray features a micro-recessed base. In the unlikely event of a leak, fluid is caught in the recess and prevented from seeping into the outer carton. This design added only a few cents per unit in cost, but it saved the client a substantial amount in after-sales expenses. b. Compression and Shock Resistance We subjected the packaging to free-drop tests from over one meter in height, repeated five to six times consecutively. Internal products showed no breakage or leakage. Key design elements included: EVA inner tray:High-density EVA die-cut inserts, precision-molded to match bottle contours. Products fit snugly with zero movement once placed inside. Outer carton board:Five-layer corrugated high-rigidity board that maintains structural integrity under a three-layer stack load. Corner protectors:Reinforced corner guards on all four corners prevent corner-collapse under stacking pressure, which is typically the first point of failure in standard cartons. c. Unboxing Ritual This was the aspect the brand valued most. We completely redesigned the unboxing sequence, transforming the act of opening a parcel from a chore into an experience: The outer layer is a flip-top magnetic closure rigid box with a soft-touch matte laminate finish — it feels silky and refined to the touch. The box front features the logo in matte silver foil stamping, with a thin gold foil accent line along the side. The moment the lid opens, the customer is greeted by a sheet of translucent glassine paper printed with the brand’s slogan. Lifting it reveals the products arranged in perfect order beneath. Beneath each product sits a small card detailing ingredients and usage tips. These layered details prompt customers to snap photos and post them on Instagram — essentially free content marketing for the DTC brand. d. Unified Brand Visual Identity From the Pantone color of the gift box (custom spot color locked to the client’s brand primary), to the grammage of the inner liner paper, to the material and print finish of the thank-you cards — we maintained full control over every touchpoint to ensure consistent brand tonality. Previously, the client had complained that packaging colors varied between batches, sometimes darker, sometimes lighter, making consumers feel “this doesn’t feel like a premium brand.” This time, we locked in Pantone color codes across the board, matching paper, ribbon, and cards under a standardized light source. e. Compliance and Market Access All packaging materials passed FDA food-contact certification (for inner tray components in direct contact with products) and FSC forest certification, among others. This ensured shipments cleared U.S. and EU customs without delays or holds due to packaging compliance issues. 3. Results Delivered Shipping damage rate dropped from over 10% to single digits; returns caused by “leakage” were nearly eliminated. Unboxing experience ratings (based on customer reviews) rose to 4 stars and above, with multiple positive reviews mentioning “the packaging is so beautiful I can’t bear to throw it away.” After visual unification, the product’s pricing power strengthened — the average order value of gift set bundles increased by nearly 20%. Complete compliance documentation enabled zero-delay customs clearance, facilitating smooth market entry into both the U.S. and EU. 4. Notes from Hanlong Engineers Many beauty brands operate under a misconception: that heavier packaging feels more premium. In reality, if a 200ml serum bottle is housed in packaging that weighs more than the product itself, not only do freight costs spike (due to volumetric weight), but consumers may form a negative impression of “excessive packaging.” Hanlong’s approach is “precision matching” — based on bottle dimensions, weight, and liquid volume, we calculate the optimal packaging size. Whether to use EVA or molded pulp for inner trays, three-layer or five-layer corrugated for outer cartons — every decision is backed by data, never made on a hunch. There is another easily overlooked detail: the paper grammage of thank-you cards and instruction sheets. Many brands use 80g thin paper that feels like a flyer. We recommend at least 200g cotton paper or specialty paper — the tactile difference is night and day. Don’t underestimate the impact of a few cents per unit; it directly shapes how consumers perceive your product’s value.

Client: European contemporary fine jewelry brand Core Needs: Supply chain integration, compliance for market entry, improved brand texture & premium feel 1. Project Background We partnered with an established jewelry brand in the European market. As the brand scaled, its decentralized packaging supply chain (boxes, inserts, ribbons sourced separately) hit bottlenecks: Inconsistent quality control Frequent color deviations High logistics damage rates The brand needed a Chinese factory that understood overseas aesthetics and could provide full compliance documentation. 2. Hanlong’s Solution We delivered a total packaging solution, not just box production. Visual Identity Unification To solve color deviations, we strictly fixed Pantone colors.All elements — outer box paper, ribbon, thank-you cards — were matched under standardized light sources to ensure consistent brand VI. Insert Upgrade Replaced low-quality flocking (shedding easily) with high-density paper trays.This eliminated complaints about lint sticking to jewelry, while precision slots secured rings and necklaces firmly in place. Full Set Accessories One-stop supply of ribbons, thank-you cards, and sleeves.We specially developed double-sided ribbon with inner core, solving the common problem of crushed bows during shipping. Full Compliance Support For EU & US export, we provided complete FSC certification and SGS environmental test reports, ensuring no customs delays due to non-compliant packaging. 3. Outcomes Delivered Simplified supply chain: no more multi-supplier coordination → greatly improved purchasing efficiency Packaging upgraded from “basic online style” to “high-end department store quality”, supporting brand price increases Full compliance enabled smooth entry into US and European retail channels Hanlong Engineer Tip Many overseas brands do not know a common factory trick: boxes may look thick but use low-density soft gray board. Hanlong insists on high-density gray board — slightly heavier and more costly, but the box stands firmly and feels solid, like a piece of stone. This is the basic standard for a luxury brand.

Hanlong Specification Snapshot Item Details Box Style Chicken bucket, combo share box, burger box Base Material 350g single‑side coated kraft paper (oil & water proof) Structure Cross‑reinforced bottom + dual‑lock lid Craft Flexo printing + spot UV + gold foil Functional Design Invisible micro‑vent system Certifications FDA, LFGB, FSC   Hanlong Engineer Tip Many fried chicken shops use cheap recycled paper, which weakens and breaks in hot oil. Hanlong uses virgin wood pulp paper for superior strength and durability. The box stays intact until the last bite. Ready to give your fried chicken shop 100% leak‑proof packaging?

  Client: Fast fashion apparel brand targeting Europe and the U.S. Core Needs: Reduce logistics damage, optimize warehouse space, improve unboxing experience 1. Project Background We partnered with a fast-growing fashion brand whose main markets are the U.S. and the U.K. As SKUs expanded, the brand faced typical growing pains in logistics: High return rates Excessive packaging waste and overstocked consumables The brand realized the issue was not the clothing, but the wrong boxes.   2. Hanlong’s Solution Instead of recommending expensive options, we designed two parallel packaging systems based on real shipping scenarios: Scenario A: Direct-to-Consumer (D2C) Shipping Solution: High-strength mailer boxes Pain points solved: Replaced tape-heavy cartons prone to tearing; self-locking bottom + double-lock lid for tape-free sealing. Material: High-rigidity corrugated paper — thin but extremely stiff, maintaining shape even with hoodies or jeans. Scenario B: B2B Overseas Warehouse Restocking Solution: Heavy-duty RSC cartons Pain points solved: Supports 3+ layer stacking; double-corrugated structure with precise ECT (Edge Crush Test) to avoid bottom-box collapse. Optimization: H-shaped taping guidelines for standardized, efficient packing at overseas warehouses. Supply Chain Integration (Turnkey Service) We also provided: Water-resistant courier bags (for T-shirts & light goods) Corrugated cushioning paper Most importantly, we optimized box proportions based on core sizes (S/M/L), reducing box types from 7 to 3 standardized sizes and cutting warehouse management costs by 20%. 3. Outcomes Delivered Lower return rate: Sturdier mailer boxes reduced damage-related returns by 15%. Cost savings: Standardized boxes cut packaging inventory; tape-free design saved thousands of dollars yearly in tape and labor. Eco-compliance: FSC-certified recycled paper meets EU mandatory sustainable packaging rules, supporting the brand’s public sustainability commitments. Hanlong Engineer Tip Many apparel brands overuse large boxes + bubble wrap for small items, wasting freight (dimensional weight) and hurting their eco-image. Hanlong’s rule: Right-sized box for each garment. We calculate the minimum ideal volume based on clothing thickness and quantity to save freight and elevate perceived quality.
